DOCX Tables to XLSX & CSV with Merged Cells
Extract main-document DOCX tables into one XLSX sheet or one CSV per table. Preserve gridSpan and vMerge as XLSX merged regions and keep header rows in place. Nested tables become separate tables with parent links. Export a CSV ZIP with merges, header rows and parent metadata.
About this docx tables to xlsx & csv with merged cells
Extract main-document DOCX tables into one XLSX sheet or one CSV per table. Preserve gridSpan and vMerge as XLSX merged regions and keep header rows in place. Nested tables become separate tables with parent links. Export a CSV ZIP with merges, header rows and parent metadata Parses and structures office document payloads locally in memory without transmitting private company files to external servers.
Document parsing & data extraction pipeline
Inspects and extracts deep metadata from Microsoft Office OpenXML document containers (DOCX, PPTX, XLSX) in compliance with ECMA-376 and ISO/IEC 29500 standards. 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: Text values only; no Word layout, formulas, images, styles, headers or footers. Nested text is excluded from the parent cell; vertical continuation text is joined at the merge anchor. Leading repeated header rows become XLSX print-title rows. CSV has no merged cells: covered cells are blank and tables.json records the structure. Values remain strings in XLSX; CSV readers choose their own types. Nonempty files below 50,000,000 bytes; main UTF-8 XML at most 10,000,000 bytes, 10,000 ZIP entries, 100 tables, 10,000 rows per table, 256 columns, 100,000 grid cells total and 256 XML levels. Invalid merge grids and legacy hMerge are rejected. Official complex DOCX and desktop Excel comparison remain unverified.
