Why @mdgate/odf
Runs where your JavaScript runs
No separate processing service. The converter is TypeScript you can call from Node.js, Cloudflare Workers, Edge runtimes, and browsers.
Local conversion
OTS files can stay inside your application or browser.
Content detection
Recognizes OTS files from their contents, not only the filename.
Deterministic parsing
The same OTS file produces repeatable Markdown without model inference.
Small runtime surface
No Python. No native addons. No WASM. No third-party runtime dependencies.
