@@MyOnlineTrainingHub The biggest one to date is around 330k rows + additional data tables with up to 15k rows which needed Power Query and Pivot to be handled properly. The result is a workbook with several dashboards for lots of different sales aspects.
My largest dataset was World Bank data which showed how much every country in the world exported to all the other countries for over two hundred different food items each for the the years 1962 to 2021. It was millions of rows and the first time my Power Query got notably slow.
I took your Power Pivot and Power Query course a couple of years ago and it changed everything! I saved so much time at work for myself and my coworkers. I get excited when someone brings me data from multiple sources that needs major cleaning, especially when they think it's going to be so tedious to sift through, because I have so many more tools now that make it much easier.
🥰Congratulations on your success with Power Query & Power Pivot! I love hearing success stories like this. I'm so pleased my courses helped you get started.
Awesome Mynda. Once I learned Power Pivot (and DAX) several years ago it completely transformed my capabilities and what I was able to accomplish in my work. I think so many Excel users still don't take advantage of what Power Pivot/DAX can do. Great video!
This is great, and what timing! I do almost all of my daily data analysis using Power BI, so I questioned if I should take the time to watch this video. But just 2 days later I was asked to do a quick analysis using an Excel extract as a data source, so I quickly did in Excel, using Power Pivot, what I'd normally do in Power BI. I wouldn't have been sure how to do that so quickly if I hadn't just seen this video. And if I discover that I'll need to repeat that analysis often, I could copy the queries I created in the Excel file's Power Query to a Power BI report or Dataflow and not have to redo anything. Brilliant!
As a plant controller, I used Power Pivot calculated measures to generate a gross profit margin based on the revenue, material, labor and overhead and helped the company improved top line revenue from the making price increase decisions on specific product models. It has modeling functionality that eliminates the need to do vlookups. This is a great tool for anyone doing data wrangling!
Mind. Blown. There is sooo much to learn from in this video, and I've been hoovering up your insights for a few months now. This ties several key tools together - I'm confident I can pull out superior information from our datasets than the native system interfaces now. Thank you, Mynda!
Hi Mynda. Thank you for this tutorial. I can tell you all "Power" features of Excel are so addictive that sometines I forget to use ol'good formulas 😉. And some tasks are easier to solve with Power tools than classic methods.
Wonderful Mynda. I am using Data model for reporting, but this technique never used till now. Really great technique and how simply explained. Two thumps up!!
7:50 Hi Mynda IMHO we should always use Fully Qualified Column Names when referring to a table column. It's about readability when using references w/o table names are used for measures. It's a kind of best practice I would say. On the other hand, I would prefer iterator functions before calculated columns. It's performing better if I'm not wrong.
I agree, in measures fully qualified table references. In calculated columns it's not necessary. Iterator functions are more efficient but they're not available for every calculation you may want to do, in which case, you can add the calculated column in Power Pivot, or if you're using Power Query, do it there before loading the data to Power Pivot.
Hi Mynda Impressive, and I would even allow myself to say that I am quite well versed in Power Pivot, but there is always something good to be gained from your review. The formula with Adjusted profit is great, I hadn't come up with it myself, thanks
Excellent video, tried and got successful.. Need a video on P&L template in Power bi with Gross profit, operating profit and net profit shown just like in excel.
Yes thanks! This is great stuff, am using it for approx. 10 years already. In the early days, it wasn't that stable yet unfortunately. It often gave errors when opening the file (due to the file allegedly not being saved correctly), or giving memory error messages whilst there was plenty (32Gb), but they seem to have fixed that by now. I work for retailers (data per product/per day etc., including history) and I believe one ot the largest sales datadump contained 30m+ records.
@@MyOnlineTrainingHub Thanks! And yes, I think the PBI / Power Pivot add-in is the greatest improvement they did on Excel since its beginning. Greetings from the NL!
This is great and I will explore and use. It seem like MSFT keeps adding and content creators are emphasizing database functions in Excel - is there any hope for the Access database program?

Remarks would have to go in the PivotTable source data table. You can't add anything to a PivotTable or even beside it and make it stay in line with the data after refresh.
Hello Mynda. I noticed recently that you can NOT group elements of a field manually when the table is in the Data Model (aka Power Pivot). Like you have a column with countries, and you want to group some from a given region, say, those in the European Union and the others. Excel will not let you do that. I agree that you should have a linked table with your countries and what group(s) they belong to, which is what I do in this case, but that may be overkill in some other situations.
Yeah, this is one of the differences with Power Pivot, but like you say, the correct way is to create a dimension table containing the grouping, overkill or not.
What is the best way to handle a sheet that has lots of rows and data. In my case, the formula and calculations are not done and not updated. So I had to increase iterations to make excel do the formulas. Can you give us the best ways to handle big files? Like which excel file format to use, ..etc
I would use Power Query to get the data from one Excel file, clean it, add calculations as required and then load it to the Power Pivot data model. Here's a demo of Power Query in action: ruclips.net/video/Nbhd0B5ldJE/видео.html
Wondering is there a preference of Calculated Columns vs Measures. Or would there be different use cases for both. It seems to me that their uses kinda overlap.

Like @hi_vishy said, you can use DAX. Power Pivot has time intelligence functions like SAMEPERIODLASTYEAR etc. you can use to write measures for use in Power Pivot PivotTables.

I guess 'data model' is more universally known, whereas 'Power Pivot' is a brand if you like. Also, it is thought that the word 'Power' is a deterrent to users who may feel it will be too advanced to even try.
@remuslupinhp "More brand name less functionality" 😂 well said. @UdaiKs you can install Parallels and install Windows OS there with Excel for Windows and full functionality, or get a PC.
I'd recommend using Power Query to connect direct to the SQL server and fetch the data (no need for VBA), but this video was just about introducing Power Pivot. I've got other videos on Power Query that you should check out if you're still using VBA to automate data gathering. This video demos using Power Query to get multiple files from a folder: ruclips.net/video/Nbhd0B5ldJE/видео.html
10:00 Wait, I’m confused… So, first you start by creating a calculated column, but now you have a measure (?) Why not just create a measure to begin with?
Access is a database, Power Pivot is a reporting too that stores data from other sources in a relational model and enables you to create reports using PivotTables. It is also available in Power BI.
The problem I have is that when importing data from folder, it does not put it in a link but puts it into the file making it a really large file. The data spans 5 years so files are large the pivot file comes in at 125mb. It is easy when linking single files as power pivot saves it as a link
That's easily fixed. Use Power Query to get the data from your external files (Excel, CSV, Text etc.) and when you 'Close & Load to...' choose 'Only Create Connection' and 'Load to Data Mode'. This will load the data direct to Power Pivot and skip also loading it to a sheet in the file.
It shouldn't make any difference where the data comes from. You just need to choose 'Close & Load To...' when first closing the query. Then you can specify where to load it to.
In Power Query I have a data model of 30.000 rows or more, by combining multiple excel files. In power Query it take up to 15 minutes just to load the preview for every step I add, and when I try to load it in my data model (whithout saving it in excel, but as a connection only), it take over 2h and a half to load in the data model. How can I work in these conditions?
30000 rows isn't the reason it's slow because this is a relatively small dataset. It'll be the way the query is written that's causing the slowness. This post has some suggestions for speeding up slow queries: www.myonlinetraininghub.com/excel-forum/power-query/any-way-to-speed-up-really-slow-refresh-times-in-power-query
I use PowerPivot from time to time, but in most cases I find it too complex for quick and easy use. Usually a simple PivotTable is all you (or at least I) need.
Not necessarily. Power Pivot overcomes many limitations of regular PivotTables with the DAX formula language. However, if you're just doing basic summarisations and aren't finding regular PivotTables limiting, then there's no reason to stop using them.
Your teaching is great, but I will appreciate if you use highlighted pointer & focus on viewers who watch your lessons on mobile phones. (Tiny screen)Your subscribers will increase considerably if you take that initiative. As of now, I may or may not view your presentations as an option. I hope you understand what I mean, & take this feedback in the right spirit.
Thanks for the feedback. I prefer to set my mouse pointer size to 200% and smooth the action to make it easier to follow. Having the pointer highlighted can also be a distraction from where you're supposed to be focusing, so it's difficult to balance.
I love your content so much. You explain things really well but the vocal fry is very quite grating. I thought to myself "Why aren't I subbed??? This is great" and then I realised why :). Just some feedback.
Interesting. I've never heard the term 'vocal fry' and had to do some research. I have a medical condition that affects my voice from time to time. It's a shame you can't see past it to enjoy my free tutorials and benefit from the content. I do hope that your reason for finding annoyance with my voice isn't as argued by Cambridge University's research paper "Girl Talk: Understanding Negative Reactions to Female Vocal Fry" where they state "when fry is heard as annoying and distracting, it is because the hearer interprets the speaker as echoing an utterance from a position of authority to which she is not entitled. We show that this reaction encodes conscious or unconscious sexist attitudes toward women's voices." Citation: www.cambridge.org/core/journals/hypatia/article/abs/girl-talk-understanding-negative-reactions-to-female-vocal-fry/AFD04ACEFCD0A0F5C08511AA9EA10504
@@MyOnlineTrainingHub I regret it too - I otherwise did enjoy your content. I'm also sorry for your medical condition. That said, I think taking it to a place centered around gender is weird and awkward. Vocal fry is grating from both men and women so my feedback was in no way related to you being a female. (That take is totally new to me). Raising that has added a layer of ick which was unexpected.
@@MyOnlineTrainingHub What do you mean by 'flexibility?' Could you give an example on this? (maybe it would be a good idea to make a video 'Why you should stick to Excel + Power Pivot and NOT move to MS Access')
It is the same! The same Power Pivot data model is in Excel and Power BI. It was originally developed in Excel, then when they created Power BI, they used the same Power Pivot data model and DAX formula language.
Pls get me a Formula to count meals (breakfasts, lunches & Diners) between 2 dates in different columns i.e 20/11/2024 Diner to 24/11/24 Breakfast BF (Column) 4nos Lunch (Column) 3nos Diner (Column) 4nos If you give me a solution i will be very greatful.
so you still used pivot tables at the end. You used the power pivot (which is old tech not new tech ). Power query is newer than power pivot. You can do all those mappings in a power query without loading it in the power pivot. Pointless video from my perspective I clicked on the video thinking i can use something else instead of pivot tables
Great to hear you’re up to speed with the Power tools. You’d be surprised how many people haven’t used Power Pivot yet. I don’t recommend using Power Query to do this as it results in a bigger file than if you use Power Pivot.
"nowadays we need/../"? You and I do not know the actual needs of others. I suppose this is a great functionality if you work in Excel a lot. A powerful tool does not equal a need.
Thanks for watching! When I said 'we,' I was referring broadly to the increasing demand for tools like Power Pivot among Excel users tackling larger or more complex datasets. It wasn’t meant to speak for everyone’s specific needs, but rather to highlight why this functionality has become important for many. Of course, not every tool is a 'need' for everyone, but for those who work extensively in Excel, Power Pivot offers capabilities that regular PivotTables simply can’t match.
@MyOnlineTrainingHub indeed. I was just in a semantic kind of mood and got hung up on the wording. Better tools are always good for those who can find a use for them. The video was quite good.
Thanks for watching my video! Regular PivotTables can't use data from multiple tables without first merging the tables into one. Power Pivot PivotTables are the only type of PivotTable that can use data from multiple tables in a single PivotTable.
Not conviced at all, you introduce database theory to people who just expect simple and clear Excel. 14 min of explanations confuse me, and you sound as Microsoft personnel, sorry.
This video is meant for those who are already comfortable with PivotTables and looking to explore more advanced techniques. Maybe the Power Query playlist will be more helpful.

I guess 'data model' is more universally known, whereas 'Power Pivot' is a brand if you like. Also, it is thought that the word 'Power' is a deterrent to users who may feel it will be too advanced to even try.
@@MyOnlineTrainingHubGood points! I just think that it would be more intuitive with consistent nomenclature.
Can I use power pivot and query on Mac Pro ?
Mac doesn't support power pivot, Mac is not the best for power bi either... More brand name less functionality...
@remuslupinhp "More brand name less functionality" 😂 well said.
@UdaiKs you can install Parallels and install Windows OS there with Excel for Windows and full functionality, or get a PC.
why not use vba and use SQL queries to fetch the data?
I'd recommend using Power Query to connect direct to the SQL server and fetch the data (no need for VBA), but this video was just about introducing Power Pivot. I've got other videos on Power Query that you should check out if you're still using VBA to automate data gathering. This video demos using Power Query to get multiple files from a folder: ruclips.net/video/Nbhd0B5ldJE/видео.html
10:00 Wait, I’m confused… So, first you start by creating a calculated column, but now you have a measure (?) Why not just create a measure to begin with?
See previous reply 😉
What’s the difference between Power Pivot and Access?
Access is a database, Power Pivot is a reporting too that stores data from other sources in a relational model and enables you to create reports using PivotTables. It is also available in Power BI.
I guess if they are getting rid of Access is is good to put the code somewhere.
I wouldn't say they're getting rid of Access, it's just not being developed much anymore.
The problem I have is that when importing data from folder, it does not put it in a link but puts it into the file making it a really large file. The data spans 5 years so files are large the pivot file comes in at 125mb. It is easy when linking single files as power pivot saves it as a link
That's easily fixed. Use Power Query to get the data from your external files (Excel, CSV, Text etc.) and when you 'Close & Load to...' choose 'Only Create Connection' and 'Load to Data Mode'. This will load the data direct to Power Pivot and skip also loading it to a sheet in the file.
@@MyOnlineTrainingHub this works when importing a single file, but does not seem to work when using and combining files from a folder (import Folder)
It shouldn't make any difference where the data comes from. You just need to choose 'Close & Load To...' when first closing the query. Then you can specify where to load it to.
Does it work in excel 2019?
Yep 😊
When I am trying to Create KPI, I got an unhandled exception error, JIT error. How to solve this issue?
Not sure. You'd have to copy the error into Google/Bing and look for a solution, sorry.
Hi, I have added a new measure, but I dont know why the filters can’t work
You're welcome to post your question and sample Excel file on our forum where someone can help you further: www.myonlinetraininghub.com/excel-forum
In Power Query I have a data model of 30.000 rows or more, by combining multiple excel files. In power Query it take up to 15 minutes just to load the preview for every step I add, and when I try to load it in my data model (whithout saving it in excel, but as a connection only), it take over 2h and a half to load in the data model. How can I work in these conditions?
30000 rows isn't the reason it's slow because this is a relatively small dataset. It'll be the way the query is written that's causing the slowness. This post has some suggestions for speeding up slow queries: www.myonlinetraininghub.com/excel-forum/power-query/any-way-to-speed-up-really-slow-refresh-times-in-power-query
I use PowerPivot from time to time, but in most cases I find it too complex for quick and easy use. Usually a simple PivotTable is all you (or at least I) need.
Yeah, I still use regular PivotTables for basic stuff.
What about power query then?
Yep, plenty of videos on Power Query in my playlist here: ruclips.net/p/PLmd91OWgLVSKnVrL0YxdOH61MAiqlFHac
6:33 - What!?!?!?!? No one in the history of ever has had this problem????? ;)
😂
Yes But, If there is no unique values ( or in unique contains duplicates) it is better to go with pivot table
Not necessarily. Power Pivot overcomes many limitations of regular PivotTables with the DAX formula language. However, if you're just doing basic summarisations and aren't finding regular PivotTables limiting, then there's no reason to stop using them.
Your teaching is great, but I will appreciate if you use highlighted pointer & focus on viewers who watch your lessons on mobile phones. (Tiny screen)Your subscribers will increase considerably if you take that initiative. As of now, I may or may not view your presentations as an option. I hope you understand what I mean, & take this feedback in the right spirit.
Thanks for the feedback. I prefer to set my mouse pointer size to 200% and smooth the action to make it easier to follow. Having the pointer highlighted can also be a distraction from where you're supposed to be focusing, so it's difficult to balance.

I love your content so much. You explain things really well but the vocal fry is very quite grating. I thought to myself "Why aren't I subbed??? This is great" and then I realised why :). Just some feedback.
Interesting. I've never heard the term 'vocal fry' and had to do some research. I have a medical condition that affects my voice from time to time. It's a shame you can't see past it to enjoy my free tutorials and benefit from the content.
I do hope that your reason for finding annoyance with my voice isn't as argued by Cambridge University's research paper "Girl Talk: Understanding Negative Reactions to Female Vocal Fry" where they state "when fry is heard as annoying and distracting, it is because the hearer interprets the speaker as echoing an utterance from a position of authority to which she is not entitled. We show that this reaction encodes conscious or unconscious sexist attitudes toward women's voices."
Citation: www.cambridge.org/core/journals/hypatia/article/abs/girl-talk-understanding-negative-reactions-to-female-vocal-fry/AFD04ACEFCD0A0F5C08511AA9EA10504
@@MyOnlineTrainingHub I regret it too - I otherwise did enjoy your content. I'm also sorry for your medical condition. That said, I think taking it to a place centered around gender is weird and awkward. Vocal fry is grating from both men and women so my feedback was in no way related to you being a female. (That take is totally new to me). Raising that has added a layer of ick which was unexpected.
Ok, but why mimic database functionality in a datasheet?
I think it would be much simpler just convert your Excel file to an MS Access database.
Because Access doesn’t have the flexibility of Excel.
@@MyOnlineTrainingHub What do you mean by 'flexibility?' Could you give an example on this?
(maybe it would be a good idea to make a video 'Why you should stick to Excel + Power Pivot and NOT move to MS Access')
Very similar to Power BI. Except the power of the relationships it seems.
It is the same! The same Power Pivot data model is in Excel and Power BI. It was originally developed in Excel, then when they created Power BI, they used the same Power Pivot data model and DAX formula language.
peace be upon you from me and zamzam water
Too bad this is not available in Excel for Mac ...
If you use Excel a lot, Power Pivot and Power Query are worth having a PC for.
You can install windows on Macs via bootcamp or an emulator. This is what I use for Excel (and it allows you to use the shortcuts you may know)
Pls get me a Formula to count meals (breakfasts, lunches & Diners) between 2 dates in different columns
i.e
20/11/2024 Diner to 24/11/24 Breakfast
BF (Column)
4nos
Lunch (Column)
3nos
Diner (Column)
4nos
If you give me a solution i will be very greatful.

so you still used pivot tables at the end. You used the power pivot (which is old tech not new tech ). Power query is newer than power pivot. You can do all those mappings in a power query without loading it in the power pivot. Pointless video from my perspective
I clicked on the video thinking i can use something else instead of pivot tables
Great to hear you’re up to speed with the Power tools. You’d be surprised how many people haven’t used Power Pivot yet. I don’t recommend using Power Query to do this as it results in a bigger file than if you use Power Pivot.
Really no different than building a crosstab query in Access. Excel has essentially replaced Access because most folks don't understand Access.
Yes, very similar to access.
"nowadays we need/../"? You and I do not know the actual needs of others. I suppose this is a great functionality if you work in Excel a lot. A powerful tool does not equal a need.
Thanks for watching! When I said 'we,' I was referring broadly to the increasing demand for tools like Power Pivot among Excel users tackling larger or more complex datasets. It wasn’t meant to speak for everyone’s specific needs, but rather to highlight why this functionality has become important for many. Of course, not every tool is a 'need' for everyone, but for those who work extensively in Excel, Power Pivot offers capabilities that regular PivotTables simply can’t match.
@MyOnlineTrainingHub indeed. I was just in a semantic kind of mood and got hung up on the wording. Better tools are always good for those who can find a use for them. The video was quite good.
People still use Excel?
12:17 So, you are forcing your using to scroll through that entire list of directors… I don’t think this is good design.
You can add the field as a filter and search for them if you prefer. Again, this is a demonstration of Power Pivot functionality for beginners. 😁
Pivot tables can already be linked to multiple data sets in the same way without using power pivot. 🤷
Thanks for watching my video! Regular PivotTables can't use data from multiple tables without first merging the tables into one. Power Pivot PivotTables are the only type of PivotTable that can use data from multiple tables in a single PivotTable.
,,,,,
Not conviced at all, you introduce database theory to people who just expect simple and clear Excel.
14 min of explanations confuse me, and you sound as Microsoft personnel, sorry.
This video is meant for those who are already comfortable with PivotTables and looking to explore more advanced techniques. Maybe the Power Query playlist will be more helpful.
