Hello there, dso0216.

Allow me to provide additional troubleshooting option that can help you export report to excel successfully.

If you've recently update your Excel version, you can revert the update. If you're not sure on how to this, I recommend seeking help from your IT professional or get in touch with Microsoft technical support. They can help you in reverting Excel updates.

If doing this doesn't work, I recommend contacting QuickBooks Customer Care so they can take a closer look and conduct a deeper investigation on what's causing the error.

Be sure to keep in touch with me here should you have any additional questions or concerns. I'm always here to help.
