# File-format parity with Microsoft Word

> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-10-11 · **Change:** trivial (Print Markup: comments in PDF/print/copies, #589; previously trivial: SmartArt written from WordCraft's model, #497; previously trivial: import/export fixes for TXT, RTF, ODT, HTML and LaTeX, #433–#440; previously major: first version; every format Word reads or writes, measured from the readers and writers on origin/main) · **Target:** Microsoft Word (Microsoft 365) for Mac 16.113.4, plus Word for Windows' extra formats

Every format Word opens or saves, what WordCraft does with it, and how it's tested. Fidelity is the
share of a typical real-world file's content and formatting that survives (read: shows correctly;
write: Word opens it showing the same). Summary in [`target-app-parity.md`](target-app-parity.md);
the work items are in [`gaps.md`](gaps.md).

**Dimension: ~60% (estimated), 179–290 h to full** (the sum of the rows below). The weighted table
gives ~64%; we discount it to ~60% because DOCX fidelity has never been checked on real-world
files. DOCX dominates the weight: a Word user sends and receives .docx; everything else is
occasional.

## Formats

Weights are the share of a Word user's file traffic (estimate). Read/write: ✅ yes, 🟡 partial,
❌ no, — Word doesn't either.

| Format | Weight | Word | WordCraft read | WordCraft write | Fidelity | Hours | How it's tested | Notes |
|---|---|---|---|---|---|---|---|---|
| `.docx` Word Document (ECMA-376 Transitional) | 70% | R/W | ✅ | ✅ | ~65% | 70–110 | `crates/docx/tests` (roundtrip 34, fixtures 29, malformed 8, bidi 5, citations 5); synthetic fixtures only | Word opens our files. Untested on a real-world corpus. Details below |

Metafile (WMF/EMF) pictures, Word 6/95 files and encrypted files are refused or dropped. No writer |
| PDF export | 8% | W | — | ✅ | ~80% | 6–10 | `crates/pdf/src/tests.rs` | krilla: embedded subsets, selectable text incl. field results (#133), links, outline, tagging. Fonts it can't subset become outlines (#132). Print Markup (#589): comments in balloons beside each page (scaled to its paper) and tracked changes; HTML/Markdown/text copies end with a comment list. No PDF/A option, no "best for printing/online" choice |
| PDF open (PDF Reflow, Word for Windows) | 1% | R | ❌ | — | 0% | 30–50 | — | Converting a PDF into an editable document. A sibling app (PdfCraft) may supply the parser |

Word's encoding choice dialog and line-ending options missing; such files save only through Save As |
| `.htm/.html` Web Page and Web Page, Filtered | 1% | R/W | 🟡 | 🟡 | ~60% | 6–10 | `crates/formats/src/tests.rs` | Tables (#102), relative pictures embedded (#113), missing `</head>` tolerated (#154). No Word "Web Page" (with `_files` folder) round-trip |
| `.mht/.mhtml` Single File Web Page | <1% | R/W | ❌ | ❌ | 0% | 3–5 | — | |

Not read: formatting changes, `w:docPr` settings, smart tags. Saving as 2003 XML is not planned (legacy) |
| `.wps` Works 6–9, WordPerfect `.wpd` (Windows) | <1% | R | ❌ | — | 0% | 10–20 | — | Windows-only converters; low value |
| Encrypted/password-protected `.docx`/`.doc` | 1% | R/W | ❌ | ❌ | 0% | 6–10 | — | ECMA-376 Agile Encryption; `.doc` RC4/XOR detected and refused (`docbin` fib). Issue #55 |
| `.xlsx`/`.xlsm`/`.ods` as a mail-merge recipient list | — | R (data source) | ✅ | — | ~90% | 1–3 | `crates/formats/src/sheet.rs`, `cmd/mailings.rs` | Read-only, one sheet's cell values (#334): shared/inline/rich strings, numbers, booleans, cached formula results, dates and times as ISO 8601 (`yyyy-mm-dd`) from the cell's number format, sparse cells; ODS value types, repeated rows/columns, covered cells.

## DOCX in depth

Measured by grepping `crates/docx/src/read` and `src/write` for the OOXML elements (2026-10-10).

| Feature | Read | Write | Notes |
|---|---|---|---|
| Text, runs, paragraph and character properties, styles, numbering, sections | ✅ | ✅ | Including complex-script props (`w:rtl`, `w:cs`, `w:szCs`, `w:bCs`…), East Asian fonts kept apart from Latin (#111), indents in characters (`w:firstLineChars`, `w:hangingChars`, `w:leftChars`, `w:rightChars`, #534); every ST_NumberFormat value of `w:numFmt` is kept on save, Chinese/Japanese/Korean, enclosed and full-width formats are drawn, the rest (Hebrew, Arabic, Hindi, Thai…) show decimal (#534). `w:beforeLines`/`w:afterLines` not kept (the points are) |
| Tables incl. floating (`w:tblpPr`), table styles and conditional formatting | ✅ | ✅ | Custom table styles round-trip (#256); right-to-left tables (`w:bidiVisual`) and sections (`w:bidi`) round-trip (#362) |
| Headers/footers (first, even/odd), page borders, line numbers, gutter, mirror margins | ✅ | ✅ | |
| Hyphenation settings (`w:autoHyphenation`, `w:hyphenationZone`, `w:doNotHyphenateCaps`, `w:consecutiveHyphenLimit`) | ✅ | ✅ | Zone, capitals and limit kept and honoured by layout (#407) |
| Footnotes, endnotes, comments | ✅ | ✅ | The document's own note separators and continuation notice (`w:type` `separator`, `continuationSeparator`, `continuationNotice`) round-trip as ids -1, 0 and 1 (#352); note options (`w:pos`, `w:numFmt`, `w:numStart`, `w:numRestart`) round-trip in the settings and in each `w:sectPr` (#385); `commentsExtended` written; `commentsIds`, modern threaded comments (`w16cex`) partly |
| Tracked insertions and deletions (`w:ins`/`w:del`), paragraph-mark revisions | ✅ | ✅ | #125, #244 |
| Formatting revisions (`w:rPrChange`, `w:pPrChange`, `w:sectPrChange`, `w:tblPrChange`, `w:trPrChange`, `w:tcPrChange`, `w:numberingChange`) | ✅ | ✅ | #41: kept on open and save, schema order (change element last); changes inside `styles.xml` are dropped. RTF/ODT ignore them |
| Move tracking (`w:moveFrom`/`w:moveTo`, `w:moveFromRangeStart/End`, `w:moveToRangeStart/End`), moved paragraph marks | ✅ | ✅ | #400: both ends linked by the range name; ranges rewritten around each moved stretch (ids renumbered); a move missing an end or a range end opens as a plain deletion/insertion. RTF/ODT/PDF export the result (moved-away text hidden like deletions) |
| Fields (`w:fldChar`, `w:fldSimple`), TOC, cross-references, `ADDIN` citations | ✅ | ✅ | Field codes Word supports but we don't evaluate keep their cached result. `EQ \o` (overstrike, enclosed characters) is drawn; enclosed characters are written as Word stores them, their style in the code's run sizes (#297); a cached picture (`INCLUDEPICTURE`) stays as the content of a range field (#465) |
| Content controls (`w:sdt`) | ✅ | ✅ | Block, inline, row and cell level, nested; title, tag, id, lock, placeholder, temporary, rich/plain text, `w14:checkbox`, combo box, drop-down list, date, picture, building block gallery, `w15` repeating sections; other `w:sdtPr` children (data binding, appearance) kept verbatim (#381). A TOC's control is rebuilt by the TOC |
| Restrict Editing (`w:documentProtection` edit/formatting/enforcement and password hash, `w:locked` styles, `w:permStart`/`w:permEnd` exceptions) | ✅ | ✅ | #412: SHA-512 hash with salt and spin count written; Word's legacy `w:cryptAlgorithmSid`/`w:hash` form (SHA-1/-256/-384/-512, ECMA-376 Part 4 §14.8.1) is kept and verified; MD2/MD4/MD5, `w:algIdExt` and other unsupported forms are refused, never unlocked; `w:colFirst`/`w:colLast` table-column ranges read as plain ranges |
| Legacy form fields (`w:ffData`), check boxes, drop-downs | ❌ | ❌ | |
| DrawingML pictures inline and anchored (`wp:anchor`), wrap square/tight/through/top-bottom | ✅ | ✅ | Tight/through read and written with their `wp:wrapPolygon` (and `edited`); without one, a shape's outline is written (a picture's rectangle). `wrapText` (both sides, left, right, largest) read and written for square, tight and through |
| WordArt text effects (`w14:textFill`, `w14:textOutline`, `w14:shadow`, `w14:glow`, `w14:reflection` in `w:rPr`) | ✅ | ✅ | Solid, gradient (linear) and no fill, outline colour/width, shadow, glow, reflection (#416); `w14:scene3d`/`w14:props3d` dropped |
| DrawingML shapes and text boxes (`wps:`) | ✅ | ✅ | Preset geometries subset (callouts and flowchart boxes drawn as the nearest shape, #611); fill and outline from the shape or from the theme through its style references (`a:fillRef`/`a:lnRef`, #611), scheme, preset, system, scRGB and HSL colours; rotation and flips (`a:xfrm` `rot`/`flipH`/`flipV`, pictures and groups too, #332), the effect extent covering the rotated bounds; `wps:bodyPr` `vert` and `anchor`, linked text boxes (`wps:txbx/@id`, `wps:linkedTxbx` `id`/`seq`, #369); text warps (`a:prstTxWarp` with adjust values, all 41 presets kept; unknown ones dropped), connectors (`straightConnector1`, `bentConnector2`–`5`, `curvedConnector2`–`5` read; 3-segment forms written) with glued ends (`wps:cNvCnPr` `a:stCxn`/`a:endCxn`; the glued shapes keep their drawing ids) and arrowheads (`a:headEnd`/`a:tailEnd`, drawn as triangles) (#416) |
| Freeform shapes (`a:custGeom`: `a:moveTo`, `a:lnTo`, Bézier curves flattened) and WordCraft ink | ✅ | ✅ | Ink is written as a freeform `wps:wsp` in a `wp:anchor` (round caps, alpha for highlighter) and recognised again by its drawing name (#307). It is saved as a custom-geometry shape, not as Word's own ink (InkML in `w14:contentPart`), so Word shows WordCraft ink as a freeform shape it can move and recolour but not erase with its ink eraser; arcs drawn straight |
| Group shapes (`wpg:`), drawing canvas (`wpc:`) | ✅ | ✅ | Groups (#267) and canvases (#344) with pictures, shapes and text boxes; nested groups flattened. The canvas schema has no transform, so a turned or flipped canvas keeps its turn in our own `wpc:extLst` extension (`urn:wordcraft:canvas-xfrm`; Word shows it unturned). Legacy VML canvases (`v:group editas="canvas"`) aren't read as canvases |
| VML (`w:pict`, `v:shape`, `v:textbox`) | 🟡 | ❌ | Pictures, text boxes, lines (with arrowheads), rectangles and ovals, best effort (#242, #611) |
| Alt text of drawings (`wp:docPr`/`cNvPr` `descr` and `title`, decorative mark `adec:decorative` from [MS-ODRAWXML]) and tables (`w:tblCaption`, `w:tblDescription`) | ✅ | ✅ | Pictures, shapes, text boxes, groups and their members, charts and SmartArt; OLE objects get theirs written into the kept XML (#386) |
| Charts (`c:chart`), SmartArt (`dgm`) | ✅ | ✅ | Drawn from the chart's cached data and SmartArt's stored drawing (#292), with data labels (`c:showVal`). Charts made in WordCraft (Insert › Chart, #409) are written as a `c:chartSpace` part with their data as literals (`c:strLit`/`c:numLit`, no embedded workbook, so Word shows them and offers to create a workbook on Edit Data) and read back as editable; a chart part holding anything more (any chart from Word, or one re-saved by Word) stays read-only. Saved back as read, with every part they reach (chart, embedded workbook, colours and style; diagram data, layout, quick style, colours and drawing) and their content types; a moved or resized one keeps its new frame, and a pasted copy gets its own parts (#319). SmartArt made in WordCraft (#497) is written from its model: data (`dgm:dataModel` points and connections), our own layout, quick-style and colour definitions under the built-in layout identifiers, and a `dsp:drawing` with every shape placed; it reads back editable only when its data part is exactly what WordCraft writes |
| OLE objects (`w:object`: embedded or linked files, ActiveX) | 🟡 | ✅ | Shown as their picture (VML or DrawingML); saved back whole with the embedding and picture parts, at the size, rotation and flips set in WordCraft (#319, #332). Can't be opened or edited |
| Word ink (`w14:contentPart`, InkML), 3D models | ❌ | ❌ | Dropped on read, not preserved on save |
| Equations (OMML `m:oMath`) | ✅ | ✅ | #191; manual breaks (`m:brk`) and the settings' `m:mathPr` wrapping options (#326) |
| Themes, font table, settings, compatibility mode | ✅ | ✅ | Embedded fonts (`w:embedRegular`) not read; attached template (`w:attachedTemplate` and its external relationship) and `w:linkStyles` round-trip (#377). The template path comes from the file, so opening never reads it: styles update from it only on an explicit Update Styles |
| Custom XML parts, document properties, bibliography sources | 🟡 | 🟡 | Custom properties round-trip; bibliography sources pending (#169) |
| Section text direction (`w:textDirection` in `w:sectPr`, §17.6.20) | ✅ | ✅ | `tbRl`, `btLr` (and `tbRlV`/`tbLrV`, read as `tbRl`); `lrTbV` and unknown values read as horizontal (#491) |
| Ruby (`w:ruby`: `w:rubyPr`, `w:rt`, `w:rubyBase`) | ✅ | ✅ | #288; base and ruby text with their run formatting, alignment, sizes, raise, language |
| Document grid (`w:docGrid`: type, line pitch, `w:charSpace`), paragraph `w:snapToGrid` | ✅ | ✅ | #391; run-level `w:snapToGrid` not read |
| `w:eastAsianLayout`, `w:fitText` | ❌ | ❌ | East Asian layout |
| Glossary document (building blocks), `w:altChunk`, sub-documents | ❌ | ❌ | |
| Hostile input | ✅ | — | `malformed.rs`, capped allocations, never-crash standard |
| Document paragraph defaults (`w:pPrDefault`) | ✅ | ✅ | Omission and explicit empty defaults remain distinct across repeated saves; nonempty defaults and later default-spacing edits are written |

## Paragraph-default preservation

The styles reader records whether `w:pPrDefault` exists. The writer keeps an omitted
container omitted when its modeled properties are still empty. An explicitly empty
container stays present, and editing document-default spacing writes the new values.
New documents and older serialized style sheets keep their explicit defaults.
`crates/docx/tests/fixtures.rs` covers omitted `docDefaults`, omitted paragraph defaults,
empty containers and populated defaults across two save/reopen cycles. This preserves
application-defined defaults without assigning inferred Word spacing values to the model.
Observed in Word for Mac 16.113.3 (26092714): three synthetic paragraph-default
controls (omitted, explicitly empty, populated) and two reduced invoice controls retain
identical text, glyph/image geometry, page sizes and embedded font-program hashes through
two WordCraft save/reopen cycles. All fifteen variants open without repair warnings.
Word PDFs and measurements remain local under ignored `plan/word/`; they are not fixtures.
These checks cover preservation on Word reopen, not WordCraft pagination parity.

The [public OOXML reference](https://learn.microsoft.com/en-us/dotnet/api/documentformat.openxml.wordprocessing.paragraphpropertiesdefault?view=openxml-3.0.1)
describes omission as leaving paragraph defaults application-defined. Real-world corpus
coverage and WordCraft layout matching remain separate gaps.

## What decides beta for formats

1. A **real-world DOCX corpus** opened, rendered and round-tripped, compared page by page with
   Word (local only: Word output can't be committed; keep a manifest and our own renders).
2. **Preserve what we can't render**: ink and drawing canvases survive a round trip
   (keep the parts and the run). Charts, SmartArt and OLE objects do (#292, #319).
3. Move tracking (`w:moveFrom`/`w:moveTo`) read and written (formatting revisions: #41; content controls: #381).
4. Encrypted `.docx` opens with a password.
