See what a workbook is really carrying: hidden sheets, hidden rows and columns, names, links, and comments.

Select a workbook. The package is parsed locally and inventoried.
Review the report: sheet visibility (including very-hidden), hidden rows/columns, defined names, hyperlinks, comments, and document properties.
Preview any sheet's contents — including hidden ones — in inspection mode.
Optionally export a copy with all sheets unhidden for full review in Excel.
Inspection is read-only. When exporting an unhidden copy, the output is reparsed to confirm every sheet's visibility state is 'visible'.
Excel supports a visibility state called veryHidden that does not appear in the Unhide dialog — it can normally only be changed through the VBA editor. Workbooks are sometimes shared with confidential data sitting on very-hidden sheets. This tool reads the visibility flag directly from the file and shows you all of it.
No. The parser reads the workbook package as data. VBA projects are detected and reported as present, but nothing is ever executed.
Open the workbook here to inventory sheet visibility, hidden rows and columns, defined names, hyperlinks, comments, and document properties in one report. The inspection is read-only and runs locally. For a second check in desktop Excel, use File → Info → Check for Issues → Inspect Document on a copy of the workbook.
No. The file is opened with your browser's File API and processed by code running in your tab. You can confirm this yourself: open your browser's developer tools, watch the Network panel, and process a file — no request carries your file's bytes. See our How it works page for a step-by-step verification guide.
