bilig

Headless spreadsheet formula recalculation and verified workbook readback

Recalculates Excel and XLSX formulas in Node.js after cell edits, without opening Excel, LibreOffice, or a browser. Fixes stale cached formula values in SheetJS, ExcelJS, and xlsx-populate pipelines that silently return wrong numbers. Verifies every edit with before/after readback, JSON persistence, and restore checks so services and agents can trust the result.

Frequently Asked Questions

FAQPage Schema
How to install Bilig?▼

Run `npx skills add proompteng/bilig --all -g -y` in your terminal to install all skills in this suite globally.

How to recalculate Excel formulas in Node.js?▼

Use the xlsx-recalc command or the TypeScript API to edit input cells, recalculate formulas, and read fresh output values without opening Excel or LibreOffice.

Why is my SheetJS or ExcelJS formula value stale?▼

Those libraries write formulas but never recalculate them, so cached values stay old. Bilig recalculates the workbook in your Node process and returns the corrected values.

Does Bilig work with Claude Code and other coding agents?▼

Yes. It ships a SKILL.md, an MCP server, and host rules for Claude Code, Cursor, Copilot, Windsurf, and many other agent environments.

Is Bilig a full Excel replacement?▼

No. It is a headless formula runtime for services and automation; macros, pivots, charts, and exact desktop Excel behavior still require a real spreadsheet app.
