Hi, yfegade.
Thank you for dropping by here in the Community. I'm here to help you export reports to excel.
Here are some reasons for the error and why you're unable to export the existing worksheet:
- There is a problem with the report or the data file itself.
- QuickBooks versions and MS Office and are not compatible.
- QuickBooks installations and MS Office are damaged.
You may also check the compatibility of your QuickBooks Desktop and MS Office: QuickBooks Desktop system requirements.
Once done, let's try closing the Excel app through the Task Manager section. It's possible that it's running in the background or multiple times which is causing this unexpected behavior.
Here's how:
- Let's press the Ctrl + Alt+ Delete key then click on Task Manager to open.
- Under the Processes tab, select Excel.exe.
- Click on End Process.
If the issue persists, let's try repairing the Microsoft Office to fix possible damaged files. After that, try to run the report again and export it to Excel.
If you get the same result, reboot your computer to close out any active programs that may be using up memory. Once the computer restarts, open QuickBooks before opening any other program.
Additionally, I've added an article for additional reference: Microsoft Office 2010, 2013, 2016, and 365 FAQ.
Keep me posted if you need some help with exporting reports. Please know I’ll be right here ready to assist further. Have a good one.
