- Опубликовано: 5 окт 2024
- What if we could control the same Excel object model we use in VBA, in Python? Well lucky for Windows users, there is a way we can leverage the Excel object model in Python with the Win32 library. In this video, we introduce our series and explore how to do basic tasks in Excel using this library.

Thank you Andrew! :)
Once again - many thanks. I have previously put some effort into integrating C# with Excel (Excel DNA) but now after switching attention over to Python for its incredible speed and libraries directed to large scale analytics, I'm excited to explore the possibilities you are sharing. For example, I have one client who is adamant on using Excel but will soon require some heavier lifting, especially in the area of machine learning and this could be the perfect opportunity for me to get into this exciting combo of technologies. Thanks again from Sydney - Dave
That's definitely one of the benefits of using Python with Excel is now we get access to so many libraries that are built for these data heavy task.
Thanks for this video. By the way, early in the video you mention that using Python gives Excel access to Dictionaries. Dictionaries can also be accessed using the Microsoft Scripting Runtime library.
Your channel is great - I'd love to see more of a 'deep dive' into win32. You can even control mouse movements and clicks; it's really powerful!
You can expect more on Win32 in the near future, it's been a very popular topic so I've been putting together some code so I can make some more videos.
Great informative video and thanks for taking the time to post it! I keep hearing how awesome Python is at automating tasks in Excel however I still struggle at understanding its value proposition especially for those comfortable w/ VBA like myself. While Python and Excel integration seems great especially given how old VBA is, features such as intellisense aren’t included which impacts development time.
It is pertinent to mention that first you have to install Win32com Lib using command on command prompt "python -m pip install pywin32". Then u can import win32com.client
A really nice demonstration. Thanks for posting.
good video. I always use and praise the OPENPYXL, but this way also look useful.
Yeah for Excel we have a ton of options, it’s really nice. I’ve been loving this Library for Access and PowerPoint
That "for i in range" loop was useless on that video... to make it work, use the previous "for CellItem in ExcRng2" loop and change "CellItem.Address" with "CellItem.Value".
By the way, nice video. Thank you by sharing your knowledge.
Excellent video...Hope to see more on this.
I'm glad you like it, It's been a very interesting topic to cover! I hope to have a video up soon where we can create a VBE like environment where we can run code in an open workbook using Jupyter notebooks. I think that will be a big help for people who are used to running code in open worksbooks!
I was wondering If I can use my SAP/vba scripts in Python, it looks like I can. After polishing my python skills I will come back to this, So I can intergrate both of these. Thanks man.
My guess would be yes, as I've seen VBA be integrated with SAP in the past.
@@SigmaCoding I was already doing VBA part, I was wondering if using python was posibble with VBA in the manner you showed, which you showed in this video. Thanks for the tutorial and the answer.
Yes, you can. I am working with Python and SAP on my daily job tasks. Just look for "SAP GUI Scripting" and you will know how to do that.
This is absolutely amazing.
Cool Man, Thx for sharing this really cool stuff
I'm sorry, I only have one thumbs up to give you. Great tutorial!
Glad you like it!
Love your videos!
Thank you for your videos. It would be very nice if you post or give us a copy of what you type because is very difficult to follow you.
Already in the process, I'm planning on making the code available on GitHub. I'll make an announcement when the code has been uploaded to GitHub.
Is it possible to load any external dll... like how we load a dll using ...Declare Function
Hello, great video. Do you know how I can activate a macro from my python code?
I added a file on my GitHub page that will walk through a simple example. Here is the link:

Can we call python script/ exe file from excel using VBA an then using python store value in excel VBA variable?
Hi! Is there a way to manipulate Pivot Tables using Python?
Yes you can, here is a simple example using the Win32COM library.
import win32com.client as win32
# Define the Excel App
xlApp = win32.GetActiveObject('Excel.Application')
# Grab the Pivot Table
xlPvt = xlApp.Workbooks("Create Pivot Table.xlsm").Worksheets("Pivot_Table").PivotTables("MyNewPivotTable")
# Print the name.
print(xlPvt.Name)
# Count the number of fields in the Pivot Table.
print(xlPvt.PivotFields().Count)
I'm new to coding and I've been confused whether to learn VBA or Python. I hear VBA is not supported anymore by Microsoft and they're thinking of migrating over to Javascript. So, do you think I should learn VBA, Python, or Javascript. I just want to be able to manipulate excel spreadsheets, combine data, shape, read, write, etc. as VBA allows, but Python/Javascript are more marketable I guess in terms of job outlook. Thoughts?
If you learn JavaScript, it sounds like it'll be primarily for the Office API. Keep in mind that API is still under development and I haven't seen a time line as to when it will be completely finished. I would focus on Python at this point only because you can still access the VBA model from it and it's just a good language overall.
You'll hear different opinions from a whole bunch of people but I personally find Python the most intuitive and user friendly. Regarding VBA, I think it'll be a long time before it's truly gone because too many companies have too much invested in it. Microsoft has already tried pulling the plug on VBA but it had mediocre results as people still kept using it.
@@SigmaCoding Thanks for answering my question! Last question, seeing that I can in fact access the VBA model with Python ... Do you recommend going the Python Win32com VBA route or Python Pandas, Openpyxl, etc route in regards to accessing the excel model?
If your goal is simply to load and transform data, stick with Pandas. Win32COM is an excellent library if you need to do more complex with the Excel application itself, but if you're just loading and analyzing data, there are better libraries.
If you're having to do things like work with data between Excel & PowerPoint or access shapes inside an Excel document, then Win32COM is for you.
@@SigmaCoding Thank you for taking the time to answer my question. Love your channel! A wealth of information and knowledge!
sir, it's opening in background, is there any way that launches it in foreground
Is there a way of selecting a populated activex combo box using python???
I'm going to have to explore this some more. I'm not too familiar with this topic, but my gut is telling me yes.
I tried to merge several Workbooks as separate Worksheets in a new Excel file with Pandas but it didn't respect the formatting. How can I do that with Win32com?
Great!!! Would you tell me how to open the existing excel file for updating the data?
Hi Steve, if you write:
import win32com.client as win32
ExcelApp = win32.Dispatch("Excel.Application")
workbook = ExcelApp.Workbooks.Open("")
that will open an existing Excel Workbook and then you would just make the updates as necessary.
@@SigmaCoding Just a note to use "\\" for the file path as opposed to just "\". Just learned that the hard way. Not sure if it was specific to my PC though.
How to process the value of excel cell having a formula using python?
Very interesting, but is not easy to see what you are tiping , its blur.
I’ll try to zoom in on the next video. Hopefully that will fix it. Also the video is uploaded as HD, I don’t know if you have it at a lower quality I’ve noticed that causes it sometimes.
Go to the Settings... then change the Quality to 720pHD. That will give you crystal clear videos with no issues at all. That should do the trick.
can you share the Jupyter notebook
It's already on GitHub, but I just realized the link isn't in the description. Here is the link: bit.ly/2VXmtAr
Also, the description should be updated.
Window doesnt open automatically when executing the code? Any ideas? Using VS Code. thanks !
This is the first video in Python VBA Model but where is the video to show how to set this up. I see this runs on localhost, do I need apache? I only used openpyxl os this is new for me.
Hey Solomon, when I made this video, I was running it in something called a Jupyter Notebook. That, in short, is really just an open-source web application we can use to share code in a "document-format". It sounds like you don't have it installed on your system. I would recommend you do the following:
1. Download Anaconda, which is a distribution of Python that comes we a lot of popular packages, including the package for Jupyter Notebooks. Here is the download link: www.anaconda.com/distribution/
2. If you want, you can just run this code in an application called Visual Studio Code. It's a lightweight code editor I also use in my Videos. Here is the download link: code.visualstudio.com/
Let me know if that gets you in a good spot.
@@SigmaCoding Will do and will watch all the videos. Thanks for the reply and hard work.
Is there specific documentation for this library? Can't find it in the interwebs
Well it depends on what type of documentation you're looking for. If you're looking for VBA specific documentation, there isn't really one for Win32COM expect for little examples here and there. If you want documentation related to pythoncom/win32COM then here is that link: timgolden.me.uk/pywin32-docs/pythoncom.html
How can i call vba macros using this feature
Is this going to be a macro in your Personal Macro Workbook or is this going to be in the workbook that has your data?
The 2nd answer to this question on Stack Overflow would help: stackoverflow.com/questions/19616205/running-an-excel-macro-via-python
Hey thanks i found out
Title says VBA but you are showing example which just use Excel Application without even touching VBA
Yeah this video was supposed to serve more as an introduction to the topic, it's not intended to go over every object in the model. Sorry, if I gave the wrong impression from the title.
However, If you look in the description you'll see links to other videos in this series. Hopefully, you'll find the content you're looking for there. :)
when i start code, python say me: "aborted (disconnected)"
Very cool. I think you made an error in your for i in ... loop. The only reason it worked was coincidence-- the celItem is referring to the cellItem from the last loop, D7, and printing out D7.value over and over again. Does ExcelRng2[i].value work?
Good catch, I'm looking back at it and I'm trying to understand why I wrote it like that because it doesn't make sense. Technically I'm just printing the last value assigned CellItem. The proper way is pretty much what you're doing up above.
ExcelRng.Cells(i, 4).Value
@@SigmaCoding That isn't correct either. i will start from 0 (zero) and thus causing an error. You could use something like this: print(excelRng2.Cells(4,i+1).Value)
