SafeShare Excel Privacy Check

Check your workbook before you send it

The included sample quote looks ready to send: 300 watches at US$29 each. A local scan locates three items for review: the Internal Costs sheet, row 4 and column D. Unhide them in Excel to see the fictional cost, negotiation floor and vendor code.

What you get

Download the skill instructions, Python scanner and sample workbook. The scanner locates hidden sheets, rows and columns, comments, external hyperlinks and declared external workbook links. The JSON report lists locations and omits cell values, comment text and link destinations.

Run locally

Unzip the package. With Python 3.9 or later, run python scripts/check.py "assets/Sample-Quotation.xlsx" from the package directory. Replace the sample path with your own file to review it. No extra Python packages or external API are required. The scanner reads the workbook without modifying it or connecting to the network.

Coverage

Supports standard unencrypted .xlsx files up to 20 MiB compressed and 64 MiB expanded. Review visible text, file properties, caches and embedded objects separately. A zero-finding report only covers the structural checks listed above. If you upload files to a hosted AI, that host handles the files under its own terms.
