Office Document Metadata Remover

About the Office Document Metadata Remover

Every Word, Excel and PowerPoint file carries more than its text: the author’s name and the company in its properties, who saved it last and when, how long it was edited, the names — and work e-mail addresses — of everyone who left a comment or a tracked change, the folder and template it came from, the printer it was set up for, and often a small picture of the first page or the GPS position inside an inserted photo. This tool shows all of it in plain words, then saves a copy without what you tick.

It edits the document’s package directly instead of re-saving it, so text, layout, pictures and formulas stay exactly as they were: parts it does not change are copied byte for byte, and photos lose only their camera data, not quality. Before the copy is offered it is read again from scratch and checked. Your original file is never changed, and nothing is uploaded: the work happens in your browser.

Common uses

• Sending a contract, proposal or report to a client without your team’s names, comments and editing history.
• Publishing a document online — on a website, in a tender or with a job application — without your user name and folder paths.
• Sharing a spreadsheet that was saved on a work computer, without its folder path, printer and the names of colleagues who commented.
• Checking what a file you received reveals about who wrote it.

What it finds and removes

• Document properties (ECMA-376 core and extended properties): Author, Last modified by, Company, Manager, Title, Subject, Tags, Comments, Category, Status, when it was created, last saved and printed, the revision number, the total editing time, the program and version, the template.
• Custom properties, such as client names or the _AuthorEmail Outlook adds when a file is sent for review, and sensitivity labels, which name your organisation’s Microsoft 365 tenant (unticked at first: your organisation may require them).
• Comments and tracked changes: their authors, initials and dates, and the list of people with their account IDs; in a presentation, also the editing records some files keep beside the slides (who made changes and when).
• Editing-session IDs (rsid) that Word writes into the text and the styles, and that can tie copies of a file together.
• Paths: the attached template’s location, the folder an Excel workbook was saved in, the hyperlink base.
• People in Excel: who reserved the workbook and who refreshed pivot tables.
• Printer settings, which name the printer and often its server.
• Pictures: the preview picture of the first page (thumbnail), and the Exif, XMP and IPTC data inside JPEG and PNG photos — camera, date taken, GPS position — removed without re-compressing.
• Stored data from SharePoint and document-management systems (custom XML), digital signatures, and the dates the ZIP container keeps for every part.

How the copy is made and checked

A .docx, .xlsx or .pptx file is a ZIP package of XML parts (Office Open XML, ECMA-376). The tool changes only the parts that hold what you ticked, and in them only the elements and attributes concerned; every other byte stays as it was. Parts it removes are taken out together with their relationships and content-type entries, so nothing points to a part that is gone.

The copy is then read again and checked: every part unpacks and matches its checksum, every XML part is well-formed, every part has a content type, and every link between parts resolves. If a check fails, nothing is saved and the page says why.

Remove names or delete comments?

Remove names keeps the discussion: each comment stays where it is, but its author and initials become “Author” and “A” and its date goes, much as Word itself does when its “Remove personal information” setting is on. (PowerPoint’s newer comments must have a date, so theirs is set to a fixed placeholder date instead.) Delete removes the comments and their marks from the text. For tracked changes the tool removes the names and dates only; the changes themselves — including text that was deleted while tracking was on — stay until you accept or reject them in Office.

Compared with Office’s Document Inspector

Office has its own cleaner: File → Info → Check for Issues → Inspect Document (Microsoft’s guide). It can also delete content such as hidden text, hidden sheets and speaker notes, and Microsoft advises running it on a copy, because what it removes cannot always be restored. This tool needs no Office installation, works on a phone, shows the actual values before you decide, and never touches your original file.

Limitations

• Old .doc, .xls and .ppt files, password-protected files and OpenDocument files (.odt, .ods, .odp) are not cleaned: save them as .docx, .xlsx or .pptx first.
• In binary workbooks (.xlsb) only the properties, the preview picture, pictures and the container are cleaned; notes and comments inside their binary sheets are not.
• It removes metadata, not content: deleted text in tracked changes, hidden text, hidden sheets, rows, columns and slides, speaker notes, macros and embedded files stay, and are listed for you to handle in Office.
• Pictures in other formats (EMF, WMF, TIFF, HEIC …) are not checked for metadata.
• Any change breaks a digital signature, so signatures are removed by default; sign the cleaned file again if you need one.
• Office writes new metadata the next time the file is saved — your name as last author, new dates — unless its “Remove personal information on save” setting is on; the tool can switch it on for Word and PowerPoint files.
