I used to be able to export all my relevant reports to Excel . But since I had to download a backup version I curently cannot convert any of them.
You have never been able to export to Excel. All exports are as TSV files. The 
button is at the lower right corner of the screen when viewing a report. You may have to scroll down to see it.
These TSV files can be opened by or imported to Excel or other spreadsheet programs. Procedures for doing so depend on your operating system and which of the many, many versions of the spreadsheet program you may have.
Hi,
I am not able to export as TSV file.
Kindly advise.
