Try @bilig/headless

npm install @bilig/headless

@bilig/headless is the public WorkPaper API for spreadsheet automation in Node services, local-first workflows, and AI-agent tooling. It can create workbooks, evaluate formulas, apply structural edits, persist and restore documents, and inspect values without opening the browser grid.

Useful entry points:

• npm package: https://www.npmjs.com/package/@bilig/headless
• package README: https://github.com/proompteng/bilig/tree/main/packages/headless#readme
• runnable example: https://github.com/proompteng/bilig/tree/main/examples/headless-workpaper
• public adoption kit: https://github.com/proompteng/bilig/blob/main/docs/public-adoption-kit.md
• launch discussion: https://github.com/proompteng/bilig/discussions/18

Benchmark evidence

The checked-in WorkPaper benchmark artifact records 46/46 mean wins on scorecard-eligible comparable workloads against HyperFormula-style workloads: 38/38 public and 8/8 holdout.

This is not a blanket p95 claim. The evidence note documents what is measured, what is excluded, and where the p95 caveat still exists:

Contributing

Good first issues are open for formula parity fixtures, WorkPaper recipes, benchmark explanation, and runnable examples:

https://github.com/proompteng/bilig/issues?q=is%3Aissue%20is%3Aopen%20label%3A%22good%20first%20issue%22

If the project is useful, a GitHub star helps more spreadsheet-automation and agent developers find it.
