Combining txt files into one text file from an Array in Power Automate.

Hello!

 

Thank you all so much for reading this!

 

I've struggled with Googling this problem, I don't want to use a 3rd party power automate library to do this.

 

I've noticed that I'm seeing a lot of help for merging into PDF and merging WORD documents on google.

Which is frustrating for me as I only want to combine text files! 

 

I guess because no one uses text files anymore? It shouldn't be too complicated ? I'm overcomplicating this?

 

I have an array within my power automate flow which contains text files like so :

APPEND TO ARRAY VARIABLE

 

NAME : FILE ARRAY

VALIE : {
"source_file_content": @{body('Get_file_content')}
}

 

How can I merge the array text files together and save them as one text file?

 

Many thanks for your help!

    I am currently looking at this to see if it can be adapted to my needs. I think the problem is that when I google for solution, all examples show a fixed array length. As you readers will know already that the array could be of any length depending on the number of files within the sharepoint document folder.

     

    I will experiment with this link above and see if I can make sense of implementing this into a loop.

    Hello Tomac and thanks for the reply.

    So the files I am merging are in a sharepoint site folder.

    I wish to merge all the text files together in date order. Each file is one month of logs.

    So there will be will be files named as follows.

    2024-01.txt

    2024-02.txt

    2024-03.txt

    I have another document folder in Sharepoint which I will drop the merged file to.

    So far my flow looks like this. I trigger saving the monthly log file via an email. This saves the file to document library in sharepoint.

    Hi! I need a bit more information about your goal to assist. Are you looking to store the text file in SharePoint/OneDrive or are you looking to have a single array with the text files for use in your Flow?
