FAQ

Can this scanner find several email addresses in one cell?

Yes. It records every distinct email-like match found in a cell.

Does it delete email addresses from my workbook?

No. It creates a separate CSV report and does not alter the uploaded workbook.

Are the detected addresses guaranteed to be valid?

No. Pattern matching finds candidates; it cannot confirm that a mailbox exists.

Which sheets are checked?

The scanner checks every worksheet in the workbook.

Is spreadsheet data sent to a server?

No. Reading and report creation happen locally in your browser.
