Is there a way to insert row into text file or merge two text files?

I have a flow that reads a SharePoint list into a CSV table and writes the correct columns to a CSV file into a document library in SharePoint. The group that is trying to read this file for import purposes wants the first row to be "UTF-8" and then the rest of the valid CSV file. As an example, the end result would look something like below:

UTF-8
name,age,country
Bob,33,US
Joe,44,US

I tried looking at doing this after the CSV table was created in the flow and before it was saved to a file but I could not see a way to merge anything with output of the CSV table. Then I tried to find a way to merge the saved CSV file with a simple one line text file that has "UTF-8" in it but all I'm seeing is PDF file merge tools you can buy from 3rd parties.

Is there no way to inject or insert a line into the CSV table or a way to merge two text documents and then save the combined results?

Hi @MattMcQ

Sounds like you want to get the CSV file and then Update the CSV file. Something like:

Hi @DamoBird365
As far as I know that will not work. Update file replaces the contents of the file. Using your example, imagine that there are two "Get file content" tasks and you want to combine the content of those and save it to a third file. What I'm missing is how to combine the two file contents into one. Hopefully that makes my question clearer.

Hi @MattMcQ

you should be able to append the get file with new content. Either use concat expression or the append to string variable option.

then update the file.

hope that makes sense.

Doh, why didn't I think of that? I have no idea what I was thinking or how I missed trying that. Here's a simple formula that seems to do what I was asking.

concat(outputs('Compose_UTF-8_line'),decodeUriComponent('%0A'),body('Create_CSV_table'))

Can we concat 2 file contents of different pdf files. I tried using the Concat expression but it gives me an empty pdf file as an output of Update the file action

For me the problem is that I can't add new rows in a csv file everytime I got a new input file. The file is overwrited. Is there any way to do this?
