Creating ZIP Folder

Posted on by adamjones_kkp

Hello,

I have a flow that takes in a zip file, extracts it to make some changes then I need to zip the file up again. The first steps work fine, and the initial HTTP request works fine and returns the token and file list as required. However the file returned from the ZIP http request when saved to sharepoint is invalid. I have put screenshots below - is there anything that is wrong or additional steps that I need to add to ensure this works correctly?

The file name and file is passed through from PowerApps, and the extracted zip and edited files are fine and accessible. Please let me know if you need any further information.

Thank you in advance,

Adam Jones

Hi @adamjones_kkp

instead of base64ToBinary function - try to use base64 function - see whether that helps ?

Thanks & Regards,

I found the solution to the issue, I just needed to add some additional JSON to the "Attachment Items" section. If anyone has the same issue I found this blog post useful: https://global-sharepoint.com/sharepoint/create-zip-file-using-power-automate/
