List folder based on the parameter passed through power app

Posted on by Community Power Pla... Microsoft Employee

Hi,

1st step - I am trying to create a flow where the flow gets the parameter(which would be partial folder name in SP library) from power apps. It then searches for the folder name in the SharePoint library using "Get Items" action and Filter OData query using substringof() formula to check folder name. Now i want this folder name to be stored in a variable which can be used to list the files in that particular folder and return the file names to power apps.

2nd step - Every folder would have a .eml file which will again have attachments in them. The attachments should be extracted and converted and merged into a PDF file and sent to power app

3rd step - similarly the same folder will have other files of different format files which again needs to be converted to a PDF format and sent to power apps.

Since power apps supports only PDF view, i am trying to convert every file to a PDF and then view it in flow.

Any help on the above query will be appreciated

HI @Anonymous ,

1- What is your current configuration on the Flow in this step? Maybe I could help you in here if you show where you are blocked.

2- I don't know of a way to extract files from .eml files. Looking into some community threads this does not seem to be supported as there are some feature requests such as this one: https://powerusers.microsoft.com/t5/Power-Automate-Ideas/Export-Email-to-PDF-format-or-convert-eml-file-to-PDF-including/idc-p/463333.

Nevertheless, in this thread i found some attempts of possible solutions that may be helpful to you: https://powerusers.microsoft.com/t5/Building-Flows/Flow-to-Extract-PDF-from-EML-that-is-attached-to-an-email/td-p/484646

3- In terms of converting files to PDF this might be tricky depending on the type of file you have. It will most of the times use the "OneDrive" connector so you can use the action "Convert File" which can convert to PDF.

I have find a few guides that maybe could help you in this part:

Hi @rimatos ,
Thanks for the response and the useful links shared.
On point 1, I was finally able to list the folder by using apply to each action on the output of Get items and then using compose and list folder. The output of list folder is now giving me the list of files inside them. But now how do I store these files in OneDrive so I can apply the next steps of converting to pdf and send the response to PowerApps.
And regarding thread for extracting the files from .eml would not work for me. since I need to extract the .eml file stored on the SP folder. But anyways thanks for providing the work around of using One-drive. Let me try that out.
