Replace Special Characters in File Attachments

(0) Share

Posted on by cds63

I have a PowerApp Form which populates a List. When the item is added to the List a Power Automate Flow runs copying the attachments to a SharePoint Document Library. Many users add attachments with special characters to the PA Form. The List accepts the files, but the SP DOC Library will not.

I’m hoping that I can find a solution to rename the attachments (replacing or deleting the special characters) in the Power App form. Is this possible?

I want to allow users to be able to add the attachments to the form and fix the problem in the Form before it’s sent to the List and Doc Library, rather than notifying the user to rename the attachments.

thanks for any assistance.

Hi @cds63 ,

This is not going to be an easy process - firstly watch this video from @RezaDorrani - it tells you how to rename attachments. Then have a read of this blog of mine on special characters. You would need to combine the two principles to achieve what you need to do.

Would it be easier replacing the special characters of the file names with a Power Automate Flow when moving the files from the Microsoft List to the SharePoint Library?

@cds63 ,

I cannot guide you on the Flow process as I have never needed to attempt it, but I suspect it would not be a simple process.
