Corrupting Excel Attachment

Posted on by mcasey

I built this flow. The creation of file works well. My problem is the email sends a corrupted attachment.

Am I supposed to use another get file after the file creation? Any other ideas?

Thanks

Re: Corrupting Excel Attachment

@mcasey I think you need to run a Get File content and a Create File action again since you are running a script after you've created the file initially.

You'll also want to ensure you are including an extension in the File Name field.

For additional troubleshooting, check the created Excel file after it's initially created and after you've run the script to ensure there isn't any issues when creating the file from Power Automate. If you are still running into issues—try switching to the Classic Designer.. the New Designer still has a few bugs.
