Office document metadata

Opens a Word, Excel or PowerPoint file and shows what is inside: the author and company in the metadata, the create and last-modified dates, title, subject, keywords, custom properties (often used by SharePoint or DLP plug-ins to store template identifiers), every accepted and pending tracked change with its author, every comment and threaded discussion. Then strips whichever groups you select. Technically: DOCX, XLSX and PPTX are ZIP containers in the OOXML format. Document metadata lives in docProps/core.xml (author, dates, title, description) and docProps/app.xml (company, application name, template path). Tracked changes are scattered across word/document.xml as w:ins / w:del / w:moveFrom / w:moveTo tags carrying a w:author attribute — every edit shows who made it. Comments live in word/comments.xml for DOCX, xl/comments*.xml for XLSX and ppt/comments/*.xml for PPTX; modern cloud threads also in xl/threadedComments or ppt/modernComments. The cleaner accepts all tracked changes (the text becomes final, history markers go away), wipes comments and the list of revision authors, and clears the identifying metadata fields — creator, lastModifiedBy, title, subject, description, keywords, company, manager, template path. Application and AppVersion are kept: those are just a label for the software, not a personal identifier. Custom properties are a separate checkbox, off by default — DLP / records-management plug-ins often write business-critical values there, and blind removal can break a workflow. Macros (vbaProject.bin), if present, are kept as-is — stripping them would kill document automation. You can drop several files at once; each is cleaned separately and the batch comes out as a ZIP. Processing happens in the browser: the document never travels to a server.
