# Bilig - Headless Spreadsheet Engine

Bilig - Headless Spreadsheet Engine is a product idea in the devtools category at difficulty 3/5, with moderate market demand and an estimated revenue potential of $1k-8k/mo.

## Summary

Lightweight spreadsheet computation engine for Node.js services and AI agents that need to handle calculations without a UI. Enable agents to work with tabular data programmatically.

## Why this is interesting

The rise of AI agents needing to manipulate structured data without spinning up a full spreadsheet UI creates genuine pull for this kind of library — LangChain and similar frameworks expose the gap clearly, as agents consistently struggle with non-trivial tabular calculations. No clear incumbent owns this space, though SheetJS handles parsing and HyperFormula (by Handsontable) covers formula evaluation, so the real competition is stitching those together yourself. The $1k–8k/mo band is realistic only through a hosted API or managed tier, since a raw npm package alone will attract stars but not credit cards. The biggest risk is that HyperFormula already solves enough of the formula-engine problem that developers just wrap it themselves rather than adopting another dependency.
