To edit Word docs without breaking formatting, you need template-preserving editing that modifies the underlying XML structure directly instead of rebuilding the file. This approach repairs and preserves layout, headers, footers, and template structure while making real edits to the document.

OOXML document repair works through unzip-based XML parsing and OpenXML validation to fix Word docx files. It targets the underlying XML structure to restore damaged page layouts, recover revisions and comments, and ensure deterministic script workflows verify the repaired file.

Yes, you can add track changes and comments to a docx file for collaborative editing and proofreading. Advanced review workflows support inserting comments, replies, insertions, and deletions while preserving the existing revision history and document structure.

Yes, offline docx creation supports template filling and chart insertion by building new Word files with OpenXML. You can add covers, tables of contents, charts, and validated page layouts to generate complete reports, papers, and business documents.

Offline Word document generation requires Python dependencies including lxml for XML parsing, matplotlib and numpy for chart generation, and playwright for rendering. These libraries enable deterministic script workflows for creating, editing, and verifying docx files.

Your docx file loses revisions because standard editing approaches rebuild the file instead of preserving the XML structure. Template-preserving editing via unzip-based XML parsing maintains revision history, comments, and formatting by modifying the OpenXML directly.
