Decompresses ZIP packages in browser memory to parse XML DOM trees: Word comment parts (word/comments.xml, commentsExtended.xml), revision marks, PowerPoint master font themes (ppt/presentation.xml, ppt/theme/theme1.xml), and embedded media archives. Exports comment threads and font audits directly to structured Excel workbooks (XLSX).

File size & structure constraints
Operational constraints and validation boundaries: Main-document text only, not Word layout or a complete historical record. Headers, footers, comments, formatting changes and moves are not interpreted. Before omits insertions; after omits deletions. Missing authors and invalid or missing times sort last; equal values keep document order. Author sorting uses Unicode code-point order; displayed times retain their original offset. Files must be nonempty and below 50,000,000 bytes, with main XML at most 10,000,000 bytes, 10,000 ZIP entries, 10,000 revisions and 256 XML levels. No official Microsoft complex-revision or desktop Word validation.
