office-open-xml-viewer is an open-source browser viewer for Office Open XML documents, rendering DOCX, XLSX, and PPTX files to HTML Canvas. Its parsers are written in Rust and compiled to WebAssembly, while rendering uses the Canvas 2D API. The README also says the full codebase was implemented by Claude through iterative prompting, making it notable as an AI-assisted software development case.
