Welcome to the PowerApps “Collections Cookbook”.
Inside you will find over 50 examples of how to do various tasks with Collections. Each page contains code and a visual to show what the code is doing.
COPY + PASTE code from the cookbook into your own app. Just change the Collection name and column names to match your own.
Add the app to a Microsoft Teams tab for instant access. I like to keep the Collections Cookbook close by while coding PowerApps. That way I can quickly look for code to solve the problem I am having and the solutions are all in one place.

I wish you the best of luck in building your PowerApp!
Thank you for your work. I learned how to convert data to a string in csv format with the Ex37 case. But I want to download a csv file down directly. I try to use the "Export" control, but the downloaded file is a zip file and the unzipped file is a json file set, which doesn't meet my requirements. I've tried other ways but it doesn't work, any suggestions?
I absolutely love your tuts, blog, and clear instructions. Saved me a lot of anguish. I am struggling with understanding how to import a msapp file into Power Apps environment and also into the MS Teams development environment which requires a zip extension. have googled it with no luck on both. I am on a Mac and do not have PA Studio but use the web based environment . Am I missing something or do something wrong as I want to look at your Collections App and learn more about them. Thanks in advance for any advice or help. Cheers Jeff
An msapp file can be imported by creating a new app, then going to the top menu and browsing to File > Open > Browse. Then you can select the file from your local drive.
If you like the Collections Cookbook please be sure to give it a Thumbs Up on the 1st page if you haven't already.
Hello Matt, thanks for the prompt response and support. Yes, will give a thumbs up, new to this, so will get onto to it asap.
I have got the msapp to import into the Power Apps web dev, as you suggested. Thanks heaps for that.
My issue is that you cannot do the same in the MS Teams App dev environment. Not sure why, but made a new app, and there is not "File - Open"
It also falls when I export form Power apps and then try to import into teams environment. Will keep trying, but the integration into teams is a bit clunky.
Got it...had to make up a new solution in Power Apps, then import apps into the new solution, then export solution with "Unmanaged" set, and then import the zip into MS teams. Finally...lol. all good.
