Hi there, @Jeff Berg.

I appreciate you sharing your inputs here in the Community about fixing the error when exporting a report to excel in QuickBooks Desktop.

This information will surely benefit other users. Also, I have here some articles about exporting MS Excel files in QuickBooks for yout future reference:

• Export option for Excel is grayed out.
• Import or export MS Excel files.

Feel free to post again if you have any questions about QuickBooks or any thoughts you might want to share.

Thank you and wishing you and your business continued success.
