HyperFormula is an open source, spreadsheet-like calculation engine ⚡

Description

HyperFormula allows you to perform spreadsheet-like calculations in your web applications. It is written in TypeScript and supports all major JavaScript frameworks. You can use it in a browser or as a service with Node.js as your back-end technology.

The engine comes with a built-in, localized library of functions grouped into different categories, and covers most user-triggered actions such as CRUD operations, undo/redo, and clipboard operations. It also supports the use of cross-sheet references, named expressions, different data types, and custom functions.

Once properly installed, you can use it like this:

import { HyperFormula } from 'hyperformula';

// define the options
const options = {
  licenseKey: 'agpl-v3',
};

// define the data
const data = [['10', '20', '30', '=SUM(A1:C1)']];

// build an instance with defined options and data 
const hfInstance = HyperFormula.buildFromArray(data, options);

// call getCellValue to get the calculation results
const mySum = hfInstance.getCellValue({ col: 3, row: 0, sheet: 0 });

// print the result in the browser's console
console.log(mySum);
