Office Viewer

Read-only preview for .docx, .xlsx, .pdf, and .pptx files directly inside VS Code.

Features

• Word (.docx) — renders text, headings, tables, lists, and styles via docx-preview
• Excel (.xlsx / .xlsm) — renders all sheets with a tab switcher via SheetJS
• PDF (.pdf) — renders all pages as high-resolution canvas via pdf.js
• PowerPoint (.pptx) — renders slides in list mode via pptx-preview

All previews are read-only. Files are never modified.

Usage

Opening a supported file automatically shows the preview. To open the same file in a different editor, right-click → Reopen Editor With….

Known Limitations

• pptx rendering faithfulness depends on the complexity of the slide (animations and SmartArt may not render correctly)
• Large PDFs (200+ pages) render all pages at once; scrolling is available but initial load may take a moment
