Scan a XLSX file
What this tool checks
Review content beyond the normal document view
- Hidden and very hidden worksheets
- Concealed rows and columns
- Formulas, defined names, comments, and external links
- Workbook properties and embedded objects
What the results mean
A hidden worksheet or formula can be ordinary workbook structure. Findings need to be verified in context and do not establish intent.
Hidden Word Scanner leaves the uploaded file unchanged and presents findings for human review. A clean scan is not a guarantee that a document is safe or complete.
