What XLSX metadata do we remove?
We clear Excel properties that expose authors or workflow while keeping the workbook intact.
- Author, company, manager, and last modified by fields
- Creation/modification timestamps and revision numbers
- Comments and sheet-level notes metadata
- Subject, keywords, category, and description fields
- Custom properties stored in docProps/custom.xml
- Application/version identifiers and template references
- Hidden workbook/worksheet part properties with editor details
- Embedded document IDs or relationships that reveal provenance
What XLSX workbooks carry beyond formulas
XLSX files are OPC ZIP packages with the same docProps tree as DOCX, but the metadata attack surface is wider because Excel adds per-workbook and per-sheet extensions that accumulate over time. workbook.xml carries a fileVersion element that fingerprints every version of Excel that has touched the file; each sheet can have its own comments part with the author name attached to every note; external data connections in connections.xml often encode server names, database names, and sometimes credentials as plain-text connection strings; and Power Query definitions in customXml parts include the full M-language query source, which is an excellent record of where the data came from (internal URLs, file-share paths, API endpoints).
Finance and HR workbooks in particular carry heavy trails: scenario manager entries include the author of every scenario, data validation error messages often contain internal reference IDs, and hidden worksheets (tagged state='hidden' or 'veryHidden') keep draft calculations that the visible sheets do not show. Cleaning sanitizes docProps, strips comments, rewrites connections.xml to remove server/path identifiers, clears Power Query source strings, removes people.xml and threadedComments, and leaves the sheet data, formulas, and formatting intact.
