How to Remove Comments from Multiple Document Files

Microsoft Office® has no out-of-the-box means for removing comments from multiple files in batch.

BatchPurifier™ can permanently remove comments from multiple files in one go. It can do so for Microsoft Word (DOCX), Excel® (XLSX), and PowerPoint® (PPTX) files, for OpenDocument Text (ODT) and Spreadsheet (ODS) files, and for PDF files.

BatchPurifier™ can also selectively remove other types of hidden data & metadata from multiple types of document, image, and media file formats. It's an offline privacy-oriented desktop application for Windows®.
