aurochs Office Viewer

View Office documents directly in VS Code — no external applications, no cloud services, no native dependencies.

All parsing and rendering runs locally in pure TypeScript.

Supported Formats

Both modern (OOXML) and legacy (OLE2/CFB) formats are supported.

Features

• Just open a file — the viewer activates automatically when you open a supported file
• Zero dependencies — all parsing and rendering is built-in; works offline, no external tools needed
• Read-only viewer — opens Office files as custom editor tabs
• Slide navigation — thumbnail sidebar with keyboard shortcuts (Arrow keys, Home/End) for presentations
• Zoom control — adjustable zoom slider for all document types
• Sheet tabs — switch between worksheets in spreadsheets
• Theme-aware — respects your VS Code color theme (light/dark)

How It Works

PowerPoint (.pptx / .ppt)

Slides are parsed and rendered to SVG. Navigate with the thumbnail sidebar or keyboard shortcuts.

Word (.docx / .doc)

Documents are rendered to styled HTML with support for paragraphs, headings, tables, text formatting (bold, italic, underline, color, font), hyperlinks, and more.

Excel (.xlsx / .xls)

Workbooks are rendered as HTML tables. Switch between sheets using the tab bar at the bottom. Merged cells, number formatting, and cell styling are preserved.
