An open-source headless spreadsheet for business web apps

- Business logic builder
- Forms and form builder
- Educational app
- Online calculator

## Installation and usage
Install the library from [npm](https://www.npmjs.com/package/hyperformula) like so:
```bash
npm install hyperformula
```
Once installed, you can use it to develop applications tailored to your specific business needs. Here, we've used it to craft a form that calculates mortgage payments using the `PMT` formula.
```js
import { HyperFormula } from 'hyperformula';
// Create a HyperFormula instance
const hf = HyperFormula.buildEmpty({ licenseKey: 'gpl-v3' });
// Add an empty sheet
const sheetName = hf.addSheet('Mortgage Calculator');
const sheetId = hf.getSheetId(sheetName);
// Enter the mortgage parameters
hf.addNamedExpression('AnnualInterestRate', '8%');
hf.addNamedExpression('NumberOfMonths', 360);
hf.addNamedExpression('LoanAmount', 800000);
// Use the PMT function to calculate the monthly payment
hf.setCellContents({ sheet: sheetId, row: 0, col: 0 }, [['Monthly Payment', '=PMT(AnnualInterestRate/12, NumberOfMonths, -LoanAmount)']]);
// Display the result
console.log(`${hf.getCellValue({ sheet: sheetId, row: 0, col: 0 })}: ${hf.getCellValue({ sheet: sheetId, row: 0, col: 1 })}`);
```

HyperFormula ships an official Claude skill and machine-readable docs, so your AI coding agent can scaffold, configure, and debug HyperFormula correctly. To install the skill in Claude Code, or to point Cursor, GitHub Copilot, or another agent at the docs, see [Set up your coding agent](guide/setup-coding-agent.md).
