HyperFormula is an open-source headless spreadsheet engine written in TypeScript that parses and evaluates Excel-compatible spreadsheet formulas. It provides ~400 built-in functions, CRUD operations, undo-redo, clipboard support, and sorting, and runs in the browser or on Node.js backends.

Use cases

• evaluate Excel formulas in a web app
• add calculated fields to a CRM or ERP
• build a custom spreadsheet-like application
• implement a form builder with formula support
• create an online calculator
• use a deterministic compute layer for AI and LLM workflows
• run spreadsheet calculations on a Node.js backend

When to choose

• you need Excel/Google Sheets-compatible formula evaluation with deterministic results
• you want spreadsheet calculation logic without any bundled UI
• you need high-speed recalculation with a dependency graph and undo-redo
• you want to embed formula-driven business logic in frontend frameworks or backend services

When to avoid

• you need a full spreadsheet UI component rather than a headless engine
• your project is incompatible with GPLv3 and you cannot purchase a proprietary license
• you need to parse complex .xlsx files with charts and formatting rather than compute formulas
• you need non-deterministic or volatile external data recalculation beyond the engine's scope
