vite-plugin-custom-functions-metadata

Vite plugin (v1.0.1) that generates JSON metadata for custom Excel functions from TypeScript source files, intended for Office Add-ins development. It scans a given input file for JSDoc-annotated functions and outputs a metadata JSON file referencing function names, descriptions, and parameters. The plugin is designed to integrate into the Vite build pipeline, automating metadata generation that would otherwise require manual maintenance. Differentiators: dedicated to Excel custom functions, leverages TypeScript type definitions, and provides a simple plugin interface for modern Vite projects. Release cadence is currently low; no breaking changes known.
