How to strip author and custom properties from office files
- Step 1Drop your Office file — Drag a .docx, .xlsx, or .pptx into the upload area.
- Step 2Wipe properties — JSZip unpacks the container, deletes docProps/* and comments, then repacks.
- Step 3Save the clean file — Download and re-open in Office — File → Properties shows everything blank.
Frequently asked questions
Does it remove track changes?+
No. Track-changes nodes live inside word/document.xml. Accept or reject them in Word first.
Will macros still work?+
Yes. vbaProject.bin is preserved, so any macros continue to function.
What about .doc / .xls (legacy)?+
Legacy formats use a binary structure. Convert to OOXML first by saving as .docx in Word.
