Is the export to Excel feature down on the Online Desktop App?
Thank you for reaching out to the Community, I'll be happy to help you export to Excel on the Online Desktop App.
Currently, there isn't an issue with this feature, so it may be something within the app itself.
Here are some steps you can try to be able to export to Excel again:
Clear QBO Windows App Data/Cache
Click Help on the navigation bar at the top.
Select Reset App Data.
Allow a moment for the process to complete, and then close the app.
Be sure to right-click the app and Run as Administrator when re-opening.
If resetting the App Data still doesn't make a difference, I recommend doing a full reinstall of the program.
Full Reinstall of the QBO Windows App:
The method for uninstalling the App varies based on which version of Windows you're using. Refer to the QBO Windows App Help Guide under the How do I uninstall? section.
Once uninstalled, you'll still need to delete the locally stored settings. Press the Windows key (⊞) on your keyboard, or click the icon (Start) on your screen and type %appdata% (including the percentage signs) in the search bar. Hit Enter.
Look for the QuickBooks folder. If you see a Roaming folder instead, open it first as the QuickBooks folder is contained within. Right-click and Delete the QuickBooks folder. This will be recreated when a fresh version of the app is installed.
Using the guide in Step 1, under the How do I install the app? section, re-install the QBO app based on the instructions for your version of Windows. It's recommended that you allow the program to be placed in the default installation directory (usually C:/ProgramFiles or ProgramFiles (x86)).
This will ensure that the QuickBooks app installs free of any older version's data or settings. Please keep me posted on if you're able to export after completing this. Thanks again, I'll be standing by for your response.
