Frequently asked questions
Which worksheet gets converted?
The first worksheet in the workbook. If the file has more than one sheet, the report tells you explicitly and only the first is converted.
Are formulas supported?
Formula cells are converted using Excel's last-saved cached value — formulas are never re-evaluated or guessed.
Is my spreadsheet private?
Files are processed privately, never used for training, and deleted automatically.
