AI Error Detection
Find the errors in a workbook before your boss does.
Scans a workbook for broken formulas, inconsistent ranges, hard-coded values inside calculations, off-by-one references and columns whose logic breaks partway down — then explains each finding and how to fix it.

Common problems and fixes
A deliberate exception is flagged as inconsistent.
Mark it as accepted in the findings list and it is excluded from this and future scans of the same file.
The scan finds nothing on a workbook you know is wrong.
The problem is likely in the data rather than the formulas. Run the Data Validator and the Workbook Analyzer instead.
Frequently asked questions
What people say
The preview before committing is the part that sold me — I could see exactly what ai error detection was going to change before it changed anything.
Fast, no signup wall, no watermark. I have sent the AI Error Detection link to half my department.
Handled a file with well over 200,000 rows without complaining. That is more than I can say for the desktop add-in we pay for.
