code-office

Showcase

Built for the review work that AI-era document flows actually create.

The extension is not an AI generator. It is the VS Code surface for the document formats that show up around AI-assisted work: generated DOCX drafts, Korean HWP/HWPX references, Markdown notes, PDFs, spreadsheets, archives, and source files that need to stay inspectable together.

Format wall

HWP, DOCX, XLSX, PDF, PPTX, and HTML stay in the same review room.

AI-era document work is rarely a single file. code-office keeps the generated brief, the Korean source form, the spreadsheet gate, the PDF evidence packet, the presentation narrative, and the HTML export visible as one workspace story.

Bundled local runtime

HWP/HWPX editing is the main product split from upstream office viewers.

The default path loads a packaged rhwp-studio build from the extension, not a remote page. The editor is wired into VS Code's editable CustomEditor lifecycle so dirty state, save, backup, revert, and format checks stay under the host editor.

Full rhwp surface

Toolbar editing, text changes, table and cell selection, and export paths are exposed through the bundled studio runtime.

Local by default

The packaged runtime is copied into resource/rhwp-studio during build. Remote studio URLs are an advanced opt-in override.

Format guardrails

Save checks preserve the destination format and reject silent mismatches before bytes are written back to disk.

File coverage

One extension for the files that usually scatter a workspace.

Family	Extensions	Mode	Implementation note
HWP / HWPX	.hwp, .hwpx	Editable	Bundled local rhwp-studio WASM runtime.
Markdown	.md, .markdown	Editable	Vditor-based authoring with inherited export paths.
Word	.docx, .dotx	Preview	docx-preview/docxjs-derived rendering.
Excel	.xls, .xlsx, .xlsm, .csv, .ods	Preview / inherited edit paths	Spreadsheet viewer stack from the office lineage.
PowerPoint	.pptx	Read-only preview	Text/media preview while deeper fidelity work remains on the roadmap.
Legacy PowerPoint	.ppt	Optional fallback	LibreOffice conversion is opt-in and disabled by default.
PDF, images, fonts, archives	Multiple	Preview	Viewer surfaces inherited and kept behind release smoke checks.
HTTP, Registry, HTML	.http, .rest, .reg, .html, .htm	Tooling / preview	Legacy runtime IDs remain for compatibility.

Install

Use a release VSIX until Marketplace publishing is intentionally opened.

Stable VS Code

code --install-extension ./code-office-<version>.vsix

VS Code Insiders

code-insiders --install-extension ./code-office-<version>.vsix --force

HWP/HWPX files are still registered through the inherited cweijan.hwpEditor custom editor ID for compatibility. Public branding and repository metadata point to this independent project. Older vscode-obsdian.hwp.* settings are read as a fallback; new HWP settings use code-office.hwp.*.

Release discipline

Packaging is treated as a smoke test, not a final afterthought.

Local gate

npm run release:local

Type-checks, builds, verifies HWP hardening, packages the VSIX, and inspects packaged contents.

VSIX inspection

Checks that rhwp WASM, NOTICE, and LICENSE are included while vendor sources, samples, docs, and scripts are excluded.

Manual smoke

Install the VSIX, open and save HWP/HWPX, then spot-check Markdown, HTML, XLSX, DOCX, PDF, PPTX, image, and archive surfaces.

Roadmap

Next work is deliberately scoped instead of hidden behind fork branding.

Obsidian-style [[wikilink]] completion, navigation, and WebView/export integration.
PPTX preview stabilization beyond text/media extraction.
Markdown CJK inline formatting and strikethrough polish.
Excel strikethrough and style preservation.
Optional LibreOffice fallback completion for legacy presentations.
