How Document Metadata Editor Works

Detailed guide to document metadata, privacy, and container structure.

Microsoft OpenXML Architecture (docProps)

DOCX, XLSX, and PPTX files are ZIP packages containing XML files. Metadata is housed inside "docProps/core.xml" (Dublin Core metadata) and "docProps/app.xml" (extended properties such as company, manager, and editing time). TagEditor parses and rewrites these XML files directly.

Critical Privacy for Resumes, Bids & Contracts

Sharing Office files without sanitization exposes past employee contributors, revision counts, corporate templates, and active editing durations to competitors and counterparties.

Safe In-Browser Archive Repacking

Using client-side ZIP decoding in browser memory, TagEditor unpacks the OpenXML container, scrubs or updates properties, and repacks a clean document with 100% native Office compatibility.
