Review for ImportExportTools NG by TomS
Rated 2 out of 5 stars
A favorite (and indispensable) add-on in times past, but starting in Oct 2021 the 'Export/Structured' option stopped working properly, and this problem has continued through Dec 2021.
Using TB V91.4 and Add-on V11.1 as of last test. The biggest issue is the failure is silent - it partially backs up the accounts, but skips all sub-folders with no (visible) indication of a problem.
