Hi Nick,
Thanks a lot for the help.
I followed the exporting to excel procedure of the first article, and I can confirm that I am exporting correctly and with the same advanced settings included in the screencapture of the article.
For the second article:
Quickbooks is updated
I use Office 365 and Windows 10, all updated to their latest version
Tried a quick repair of Office 365
Reinstalled Office 365
Deactivated UAC
Uninstalled and reinstalled Quickbooks, then updated it to it's latest version
As mentionned, the problem is just that the data fields are exported as text instead of numbers, and must be converted manually. (which becomes a long process)
Would there be anything else to try?
Thank you
