QB desktop pro 2019 crashes when I export to Excel

You're right, Marcia.

Exporting reports to Excel requires Microsoft Excel 2016, 2013, or 2010 or Office 365. QuickBooks Desktop will receive an error or crash if you're using an unsupported version.

You may need to update to make it work moving forward. You can check this article for more system requirements for QuickBooks 2019 and Enterprise Solutions 19.0: https://quickbooks.intuit.com/learn-support/en-us/product-preferences/system-requirements-for-quickb....

I appreciate your understanding regarding this matter.
