What this tool does
This audit creates a separate XLSX report of content that may not be obvious in the normal worksheet view. It does not unhide or edit the uploaded workbook.
Workbook structure + cell features → categorized hidden-content findings
SheetJS exposes many common workbook features, but drawings, macros, external links, and every Excel-specific object cannot be fully audited in a browser.
Supported formats
Files are processed locally. XLSX and XLS workbooks are read with SheetJS; CSV and TSV files are parsed with delimiter-aware handling. Advanced Excel features may not be preserved in generated files.
| Format | Support |
|---|---|
| XLSX / XLS | Read workbook values and formulas |
| CSV / TSV | Read delimited rows |
| Output | New downloadable file or report |
Tips for better results
- Work from a backup when the source workbook is important.
- Keep identifiers such as ZIP codes and account codes stored as text.
- Review the bounded preview and downloaded result before replacing any business workflow.
FAQ
Which hidden workbook content is reported?
The scan covers hidden sheets, hidden rows and columns, comments, formulas, hyperlinks, defined names, and selected document properties when exposed.
Does the report unhide anything?
No. It reads the workbook and creates a separate findings file without changing visibility settings.
Can it detect hidden macros or every external connection?
No. Browser libraries cannot fully inspect VBA projects, Power Query, drawings, or every Excel connection object.
Are very hidden worksheets distinguished?
Yes. When the workbook exposes that state, the report labels a sheet as very hidden rather than normally hidden.
Is a formula considered hidden content?
Formulas are listed as potentially non-obvious logic, but their presence is not itself a privacy or security problem.
