Frequently asked questions
What metadata can an Excel workbook contain?
Author and company names, timestamps, custom properties, hidden worksheets, comments, drawings, and external links can all travel inside an XLSX package.
Is my Excel file uploaded?
No. Inspection runs locally in your browser, without storing or transmitting workbook contents.
Does this support XLS or XLSM?
No. This safety-focused tool accepts standard XLSX workbooks only. Legacy XLS and macro-enabled XLSM files are rejected.
