Another great video Reza, will be directing all the folks who want to start using Power Automate here! I watched another video recently talking about trigger conditions and they had a great tip of using the filter array option to build your trigger condition expression, really simple and switching from basic to advanced view gives you the trigger condition expression you need (including the @)
Awesome, thank you!
Your 💡 is awesome as well.
That Video was by Damian Bird. Really useful trick to get those trigger conditions worked out.
@@Worrelpa yes it was, I like a lot of his stuff!
Cheers guys - appreciated 👍
He does a great job - gets right to the point - doesn't waste any time - very concise - very knowledgeable.
He says Thank You :)
And his mic quality is actually good! Unfortunately so many of these talented developers making content have thick Indian accents, although they can’t help it - this makes it hard to understand coupled with bad microphones its doubly difficult to comprehend the great info they teach: shout-out Reza! 💪🏼
Almost a year later after this video and you're still helping out beginners like me. Thank you, Reza!
So happy to hear that
Amazing video! Thank you so much!!!
I was searching for a good content that explains how to build expressions for months and finally found answers to most of my questions in your single video :)
Great to hear! Thank You so much for watching.
Hi Reza. I just had to share this with you. I used your video named "Power Apps Save Pictures to SharePoint - Camera Control Tutorial" . The comments were turned off, so I am using this video's comments section. Whenever I wanted to submit the attachments I kept on getting a warning that the "Id" was needed for the form submit. It took me nearly 5 hours of swearing and crying to realize, after watching your video over and over again, that I had used "ID", instead of "Id" in the JSON schema. The warning message was telling me the fault all along. Now I am laughing at myself. Thanks for all your help, I and I sure many others, really appreciate it.
Thanks for sharing the details Ashley. Glad to know it worked :)
The comments are turned on for that video. I have a lot of recent comments on that video.
Thank you sooo much!!! I'm not even sure you realize how helpful your videos are. You have a multitude of tips and helps in this video alone. I've been struggling with 1 thing... I was not able to see the add dynamic content/expression editor button. After trying several things and numerous searches, I was feeling defeated. But you casually mentioned it in this video. I am grateful! That's only 1 example. There are many more!!! Thank you!
Wow! You are most welcome! So glad to hear the video is useful and packed with content.
Thank you for FINALLY explaining the use of the ? in traversing json! I've seen/read dozens of blog posts or videos where they just give the notation without explaining it.
Glad it was helpful!
Reza, you have shown me so much and answered many questions - thank-you!
Most welcome
Honestly - Whenever I face any challenge anywhere in Power Platform, Preferably I always look for your videos because of you pick complex tasks in your videos which covers other multiple scenarios....You helped me a lot. Thank you Reza...Cheers!
Wow! Thank You so much for watching and learning from the videos. Much appreciated.
Absolutely awesome, no one can explain that better than you.
Thank You 😊
Massive thanks Reza! - I always found myself going back to the 101,201.... series you had done w/ Jon L.... but I now have new supercharged, super-concise reference for PA expressions!..
With a vast array:) of excellent use cases - Well and truly bookmarked! 🔖
Thanks Gerard.
Goal was to make a one stop shop video and cover all aspects of expressions with real world use cases.
Excellent tutorial. Very timely as I'm currently working on flows where I'm having to use a lot of expression. Thanks for sharing.
Glad it was helpful!
Excellent! Exactly what I was looking for. Thank you!
Great to hear!
Best Power Platform Developer ever, thank you for your amazing videos ❤️
Wow, thank you!
Reza your videos are Awesome! All facts! Thank you
Thank you very much for such detailed explanation step by step! 👍
You are most welcome!
Hi Reza, thank you for all your efforts in creating videos. You're the best in terms of the content and making each steps understandable, dare I say better than Jon Levesque and Jon is great!
Thanks Alex.
Thanks Reza for sharing your knowledge..please keep up the good work you are doing for the community.
My pleasure
Like always BRILLANT!!
Thanks, Reza
Thanks Gourav
Thanks Reza, a gold mine of information there as usual.
I struggle with the new editor, I probably just need to get used to it and practice more.
Always find myself going back to the classic one. Sure the expressions are harder to edit, but I drop them out to an editor first then copy paste them back in. Something about that makes it easier to compare expressions and see those silly errors. Quotes, comma, brackets missing etc.
One of the things I have started to do with expressions is when I have collected data is to create an array of items I need and use on the flow. Then inside that array use expressions to do any conversions or processing I can do against them to save on compose and variable steps. e.g. from SharePoint get item, take any date / time fields and convert into various formats and have them as their own items directly further down the flow. With those items I also add expressions inside If(Empty(Item), 'no value', converttimezone) etc In cases where fields are not required fields to avoid some failures.
Looking forward to the next one. This video will be in my video reference library. ;)
Thanks Phil.
Your tips are awesome!
Thank you Reza for this wonderful video.
You are very welcome
This was most awaited video! Thanks Reza!

Great video, Amazing Power Automate content in a single 35 min video. Request you to make something for Batch add/delete or some other batch process using power automate.
Thank You.
I will add the batch process request to my backlog.
Thanks Reza 👌
You are most welcome
big thank from VietNam
Most welcome
Thank you Reza for another great video. I really thankful for the guidance on avoiding loop. Regarding parsing Json can you please guide how we can apply query or filter on the parsed json to get only specific data by matching some string?
I have done several flow videos where I have used the Data Operation action "Filter" .
Thank you Reza. That was a real dive in. Would you think of an equivalent GetItems action but against Dataverse table? So with one action, we could filter a table on multiple columns. List Rows( filter rows) seems to accept only one column at a time.
It does support multiple filters.
I will have to look at your flow in action to know more about your issue. I would recommend you post your issue/query with screenshots on the forums at powerusers.microsoft.com
Hi Rezza, Appreciate to this truly awesome content. I was having a question, does power automate expression have left, right, mid etc. string functions. ?
It does not. You would need to use substring function.
Thanks for another great video. Have a question: We are checking if we could store some business rules as expressions in dataverse tables and then invoke them in Power Automate based on needs.
Never tried that scenario. Probably would be possible.
Thank you Reza, I had lost my expression builder and could not understand why. You showed me that my browser resolution was too high, it was driving me nuts.
👍
Great as always. Can you make a video on your vidéo recording and editing process :D ? Maybe you use power platform in the process :)?
Thanks Jeff.
I use Camtasia to record and edit my videos.
I take on average 4-6 hours per video for recording and editing.
Hi Reza!!! Commendable Videos.
Kindly suggest for below mentioned issue
I have a table with multiple mail IDs. Flow generated same number of mails as per IDs. (If mail id is 4 times, it will send 4 mails with HTML table)
Rgds
I do not have a specific video on that use case.
May be this video helps ruclips.net/video/tp0jLnmKcEs/видео.html
Hi Reza, thanks for the video. I have a question. So, I am trying to automate feedback forms where there's a column named 'Additional Comments' and users enter comments with a newline. As soon as a new line is encountered in SQL, it goes to next column and hence not taking the data properly. I was thinking if I could replace the newline character in the flow with a space character. Please let me know how to proceed with this problem. Thanks :)
I do not have a video reference on this scenario and would have to try it out to provide guidance. I would recommend posting your issue/query with screenshots on the forums at powerusers.microsoft.com
Thank you for the video !! Could you please help to write an expression in power automate. If Column A is less than or equal to Column B then output should be column C else output should be column D. I have developed a workflow and trying to write the expression in "SELECT" tool where the output from If condition should be captured. Please help. Thank you
If(lessOrEquals(a,b),c,d)
It would be ideal to look at screenshots of your flow in action. I would recommend to post your query with screenshots on the forums at powerusers.microsoft.com
Amazing Video.. Please see if you could slightly reduce the pace in the upcoming videos
I have got my pace down from about 2 years ago :)
I will work on going one level slower. Thank You for the feedback.
Hey Reza thank you for sharing this amazing knowledge I do question please try reply it
How can I shows custom fields value which are in dataverse.
Basically I am creating custom update from and I need to show user there fields value which they have created while submitting from Canvas
How can I achieve this
Database : dataverse
I do not have a video on this use case. I would have to try it out to provide the steps.
I will recommend you check on the forums at powerusers.microsoft.com/
Do you know maybe how to replace a select action with an expression (to create array from one JSON property)?
It depends on the data structure.
If I have a string a,b,c,d and using split it will create an array.
There are options and it differs based upon the use case.
14:13 Would it be possible to convert the date/time to the user's local time zone, meaning the result shows differently based on the user's location? Thanks for sharing.
As long as you have info of users local time zone while running the flow, you can do that.
Thank.
Hi Reza,
Your posts and videos are awesome and very helpful. I posted questions on the comments today and last week. For some reason I do not receive comments and my questions ate missed from the posts. Did anyone have idea on those?
Thanks!
Thanks for liking my videos.
Which platform are you unable to post comments on? RUclips or the community forums?
@@RezaDorrani I posted a question how to get/retrieve user groups (group names) and Permission level of each group in a site using power automate. I am able get each separately, but unable to map them, that is a user group to it's permission level. Your clues and idea are so helpful.
Thanks for reaching out!
@@gayirga3825 I would recommend to post your issue with screenshots on the forums at powerusers.microsoft.com
@@RezaDorrani Sure will do that.
@@RezaDorrani Thanks!
Hey reza this is great. however Im not able to edit the expressions in the dialog box. are u aware of this bug? not sure who can i raise this to. possible to advice?
also, isit possible to trigger an approval based on a particular input of a form using an expression?
for eg.
If form contains a particular response, send approval to A. If form contains a different response, send approval to B.
Not aware of any such bug. I would recommend posting your issue/query with screenshots on the forums at powerusers.microsoft.com
Hi Reza, as per your advice I posted the issue on the Power Automate Community site.
Site groups generated using (_api/Web/SiteGroups) in http request, and Roledefintions generated using (_api/Web/RoleAssignments?$expand=Member,RoleDefinitionBindings) in different http request. Both are within the same flow. I am trying to map Group Name (from _api/Web/SiteGroups) output to Permission Level (in _api/Web/RoleAssignments?$expand=Member,RoleDefinitionBindings) output.
Tried Compose, Select, ... in Data Operation including loop, but unable to achieve.
Thanks!
I will have to look at your flow in action to provide guidance. Forums would be your best bet.
I myself go to assist in the forums but only in my free time.
@@RezaDorrani That is great! Thanks Reza as always!

Hello Reza, I have a question, why in 13:18 your expression "and" that has "startsWith" and "endsWith" expressions inside gave you true? Especially "endsWith" expression with second parameter as 'd'? It should have returned the false as your string 'Reza Doranni' doesn't end with letter 'd'.
the actual expression was showcased at 12:34
13:18 - shows the static expression text that I mistyped.
@@RezaDorrani Thanks for your clarification and for your great content👍
