Generate a collection from CSV format data sent from flow - string format is below - needs a formula for splitting them

[IAmTheAppUser]

String format:

streetNumber,streetName,Suburb,Postcode,State,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx,xxxxx

The above string is the format parsed from Flow to Powerapps. I want to be able to turn it into a collection.

The first five comma separated values would be the title. The rest of the comma separted values would be sequentially matched to each title which is represented by 'xxxxx' in the string. In the above string, there are 15 'xxxxx' which indicates that there are three addresses returned from Flow to Powerapps.

I want to be able to split them so that I can show them in a collection with 5 heading at the beginning of the string.

Thanks for the help 🙂

Hi @IAmTheAppUser 

If you have license to use Premium connectors, then you can directly use the Response action to send JSON to PowerApps. This can be collected in a collection using ClearCollect(CollectionName,FowName.Run())

Once you make any changes to the flow, you need to remove it and register it again to the canvas app.

If you do not have license for premium connectors then you can use below expressions:

Clear(MyCollection);With({Loops:(CountRows(Split(Label1.Text,","))/5)-1},ForAll(FirstN([1,2,3,4,5,6,7,8,9,10,11,12,13,14,15],Loops),Collect(MyCollection,{streetNumber:Last(FirstN(Split(Label1.Text,","),Value+5)).Result,streetName:Last(FirstN(Split(Label1.Text,","),Value+6)).Result,Suburb:Last(FirstN(Split(Label1.Text,","),Value+7)).Result,Postcode:Last(FirstN(Split(Label1.Text,","),Value+8)).Result,State:Last(FirstN(Split(Label1.Text,","),Value+9)).Result}))) 

Note: We cannot pass variable the keys for name of columns in collections, hence this needs to be harcoded. Here, you need to replace Label1.Text with the value that holds this returned string.

Hope this Helps!

Hi Yashag2255

The functionality of my app gets the files name in one drive. Then the user selects the file name in the app. The app then triggers the flow to get the file content.

Is there any way in Flow to parse the data in the user selected file into Json? If there is one, I could just parse the data from the file as Json, else, I would have to trigger a Azure function in flow that sorts the format of the data.

Thanks for help 🙂
