When uploading an .xlsx file into a SharePoint list, the file gets corrupted

Hi,

 

When uploading an .xlsx file into a SharePoint list, the file gets corrupted, ie, it doesn't open anymore.

 

Is this a bug? Any ideas, please?

 

Thank You.

Xlsx and XLS are different file formats.  The extension used when uploading the file is set by the person uploading the file.  There is no way to determine in Power apps which it should be.  The user who is submitting the file needs to use the correct extension.  .XLS is a legacy format and really should be avoided if possible.

How are you uploading the file?  Are you sure the .xlsx file extension is being maintained?

@Pstork1 

I'm uploading the files with a Form.

What do you mean with "being maintained"?

 

Thanks!

So you are using the Attachments control in the form?

And the file that is showing in the attachment control has an .xlsx extension?

I'm not sure what is happening then.  I seen this happen if SharePoint loses track of the extension and it becomes just a file, but I haven't seen it any other time.  I just tried it again in a test app and it works fine for me.

In our case, some files are uploaded correctly and others become corrupted and we don't know why.

@Pstork1 

Is there a way, to simply convert .xlsx into .xls?

Maybe that helps..
