Old binary .ppt files were an embarrassing gap. A browser viewer that asks users to convert an old deck before opening it isn’t doing its job.

File Viewer 2.2.0 fixes that gap and removes a long list of failures around Worker paths, subpath deployments, PDF.js versions, OFD image placement, and large text files.

What’s new

  • Binary PowerPoint 97–2003 .ppt preview now runs directly in the browser through @file-viewer/ppt@0.3.1.
  • PPT and PPTX stay on separate rendering paths. Both support the shared zoom, print, and export flow.
  • The complete PPT Worker, WASM, CJK font, and frame-cache runtime is bundled with the Demo, Full packages, copy-assets, CDN/IIFE, and Vue 2.6 + Vue CLI 3 example. Standard deployments need no manual PPT URL setup.
  • The format matrix now covers 208 extensions across 25 preview pipelines.
  • The main Demo is now an immersive document workspace. Controls stay fixed while only the document container scrolls. Explicit ?url= links open directly into the focused viewer on desktop and mobile.
  • Runtime asset paths now follow one shared resolver across Vite, Angular, Vue CLI, Webpack, nested routes, relative bases, Windows paths, spaces, Chinese directory names, and folders named assets, static, or js.
  • CAD uses @flyfish-dev/cad-viewer@0.7.0. STEP/STP, IGES/IGS, and BREP files render through the local OCCT Worker/WASM path.

Fixes

  • Fixed PPTX styles inside Shadow DOM and Worker URLs under subpaths (#127, #129).
  • Fixed PDF centering in flex/scroll containers, host PDF.js global conflicts, and stale API/Worker version mismatches (#128, #134, #138).
  • Fixed OFD images being placed at the top-left when CTM offsets were relative to the image Boundary.
  • Fixed GBK/GB18030 CSV and TSV decoding, added optional text line numbers, kept large Markdown rendered by default, and added text.toolbar (#124, #125, #136, #137).
  • Fixed OOXML files incorrectly named .doc (#131).
  • Added the missing Spreadsheet Worker to non-Full preset-office asset delivery (#135).
  • Removed runtime GitHub API requests and root-path assumptions from distributed offline assets.

Tested before release

The final gate ran:

  • 354 unit tests across 72 test files
  • 136 real bundled sample files
  • 232 visible sample-card clicks across Chinese and English Demo views
  • All 25 preview pipelines
  • PPT and PPTX in 10 Full-package browser integrations
  • 54 release tarballs
  • 15,800 offline runtime files
  • OFD placement checks across 5 files, 101 pages, 210 images, and 6 seals
