Hello there, @Anonymous.

Allow me to join this thread. The investigation about the error you encountered when exporting a report to Excel is still an ongoing issue. 

Though some users were able to export their report by following the workaround provided by @HWS, others were not. You can run the report and copy then paste it directly to Excel until a resolution is found.

In case you haven’t given our Customer Care Team a call to add your account to the list of affected users, please do so. Just ask the phone agent to attach your case number to INV-23844, so you’ll be notified of any updates available once received. 

You can find our contact information through this article: Get help with QuickBooks Online. 

We thank you for your patience and understanding. Please let me know how it goes by leaving a comment below. I’ll be on a look out for your response.
