See what an Excel workbook contains before you share it.

Inspect metadata, hidden sheets, comments, timestamps, external links, connections and cached data. Edit safe metadata locally; review anything that could change workbook behaviour.

MetadataEdit authors, company, dates and custom properties individually or in bulk.
Hidden structureFind hidden and very-hidden sheets, rows, columns and defined names.
External dependenciesSurface workbook links, data connections and where formulas reference them.
Safe outputReopen the generated XLSX and verify untouched package parts stayed byte-for-byte identical.
