## About

Rust/WASM parsers and Canvas renderers for DOCX, XLSX and PPTX, with document APIs and ready-to-use viewers.

DOCX, XLSX and PPTX parsing is implemented in Rust and compiled to WebAssembly.

The implementation refers to ECMA-376 / ISO 29500 and related Microsoft documentation where relevant.

Use built-in viewers or document APIs for custom previews, thumbnails and navigation.

Switch formats, navigate pages or slides, and scroll the sheet.

Selected supported features for each format are listed below. See the README for the full matrix; complex documents may still differ from Office.
