# DOCX Processing

`.docx` is a ZIP archive of XML and resources. Different tasks have different tools and workflows.

## Workflow Decision

| Intent | Workflow | Reference |
|--------|----------|-----------|
| **Read/analyze text only** | pandoc → markdown | [raw-xml-access.md](references/raw-xml-access.md) |
| **Read structure, comments, media, formatting** | unpack → raw XML | [raw-xml-access.md](references/raw-xml-access.md) |
| **Create new document** | docx-js (JS/TS) | [docx-js.md](docx-js.md) |
| **Edit own document, simple changes** | Document library (Python) | [ooxml.md](ooxml.md) |
| **Edit someone else's document** | Redlining (tracked changes) | [redlining.md](references/redlining.md) |
| **Legal / academic / business / gov docs** | Redlining — REQUIRED | [redlining.md](references/redlining.md) |
| **Visual analysis** | soffice → PDF → pdftoppm | [raw-xml-access.md](references/raw-xml-access.md) |

## Text Extraction (Quick)

```bash
pandoc --track-changes=all path-to-file.docx -o output.md
# --track-changes=accept/reject/all
```

## Create New Document

1. **MANDATORY — READ ENTIRE FILE**: `docx-js.md` (~500 lines). NEVER set range limits.
2. Create JS/TS file using Document, Paragraph, TextRun components.
3. Export with `Packer.toBuffer()`.

## Edit Existing Document (Own, Simple)

1. **MANDATORY — READ ENTIRE FILE**: `ooxml.md` (~600 lines). NEVER set range limits.
2. `python ooxml/scripts/unpack.py <office_file> <output_dir>`
3. Run Python script using Document library.
4. `python ooxml/scripts/pack.py <input_dir> <office_file>`

## Edit Someone Else's Document → Redlining

See [redlining.md](references/redlining.md) for full 6-step workflow with batching strategy and RSID preservation.

## Code Style

- Write concise code, no verbose variable names, no unnecessary print statements.
