It can be integrated into your browser or utilized as a service with Node.js as your back-end technology.\n\n## What HyperFormula can be used for?\nHyperFormula doesn't assume any existing user interface, making it a general-purpose library that can be used in various business applications. Here are some examples:\n\n- Custom spreadsheet-like app\n- Business logic builder\n- Forms and form builder\n- Educational app\n- Online calculator\n\n## Features\n\n- [Function syntax compatible with Microsoft Excel](https://hyperformula.handsontable.com/guide/compatibility-with-microsoft-excel.html) and [Google Sheets](https://hyperformula.handsontable.com/guide/compatibility-with-google-sheets.html)\n- High-speed parsing and evaluation of spreadsheet formulas\n- [A library of ~400 built-in functions](https://hyperformula.handsontable.com/guide/built-in-functions.html)\n- [Support for custom functions](https://hyperformula.handsontable.com/guide/custom-functions.html)\n- [Support for Node.js](https://hyperformula.handsontable.com/guide/server-side-installation.html#install-with-npm-or-yarn)\n- [Support for undo/redo](https://hyperformula.handsontable.com/guide/undo-redo.html)\n- [Support for CRUD operations](https://hyperformula.handsontable.com/guide/basic-operations.html)\n- [Support for clipboard](https://hyperformula.handsontable.com/guide/clipboard-operations.html)\n- [Support for named expressions](https://hyperformula.handsontable.com/guide/named-expressions.html)\n- [Support for data sorting](https://hyperformula.handsontable.com/guide/sorting-data.html)\n- [Support for formula localization with 17 built-in languages](https://hyperformula.handsontable.com/guide/i18n-features.html)\n- GPLv3 license\n- Maintained by the team that stands behind the [Handsontable](https://handsontable.com/) data grid\n\n## Documentation\n\n- [Client-side installation](https://hyperformula.handsontable.com/guide/client-side-installation.html)\n- [Server-side installation](https://hyperformula.handsontable.com/guide/server-side-installation.html)\n- [Basic usage](https://hyperformula.handsontable.com/guide/basic-usage.html)\n- [Configuration options](https://hyperformula.handsontable.com/guide/configuration-options.html)\n- [List of built-in functions](https://hyperformula.handsontable.com/guide/built-in-functions.html)\n- [API Reference](https://hyperformula.handsontable.com/api/)\n\n## Integrations\n\n- [Integration with React](https://hyperformula.handsontable.com/guide/integration-with-react.html#demo)\n- [Integration with Angular](https://hyperformula.handsontable.com/guide/integration-with-angular.html#demo)\n- [Integration with Vue](https://hyperformula.handsontable.com/guide/integration-with-vue.html#demo)\n- [Integration with Svelte](https://hyperformula.handsontable.com/guide/integration-with-svelte.html#demo)\n\n## Installation and usage\n\nInstall the library from [npm](https://www.npmjs.com/package/hyperformula) like so:\n\n```bash\nnpm install hyperformula\n```\n\nOnce 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.\n\n```js\nimport { HyperFormula } from 'hyperformula';\n\n// Create a HyperFormula instance\nconst hf = HyperFormula.buildEmpty({ licenseKey: 'gpl-v3' });\n\n// Add an empty sheet\nconst sheetName = hf.addSheet('Mortgage Calculator');\nconst sheetId = hf.getSheetId(sheetName);\n\n// Enter the mortgage parameters\nhf.addNamedExpression('AnnualInterestRate', '8%');\nhf.addNamedExpression('NumberOfMonths', 360);\nhf.addNamedExpression('LoanAmount', 800000);\n\n// Use the PMT function to calculate the monthly payment\nhf.setCellContents({ sheet: sheetId, row: 0, col: 0 }, [['Monthly Payment', '=PMT(AnnualInterestRate/12, NumberOfMonths, -LoanAmount)']]);\n\n// Display the result\nconsole.log(`${hf.getCellValue({ sheet: sheetId, row: 0, col: 0 })}: ${hf.getCellValue({ sheet: sheetId, row: 0, col: 1 })}`);\n```\n\n[Run this code in StackBlitz](https://stackblitz.com/github/handsontable/hyperformula-demos/tree/3.0.x/mortgage-calculator)\n\n## Contributing\n\nContributions are welcome, but before you make them, please read the [Contributing Guide](https://hyperformula.handsontable.com/guide/contributing.html) and accept the [Contributor License Agreement](https://goo.gl/forms/yuutGuN0RjsikVpM2).\n\n## License\n\nHyperFormula is available under two different licenses: GPLv3 and proprietary.
