# Handsontable

> Handsontable makes two JavaScript products: Handsontable DataGrid, a data grid with a spreadsheet look and feel, and HyperFormula, a headless spreadsheet calculation engine written in TypeScript.

The two products integrate natively: HyperFormula is the engine behind Handsontable DataGrid's Formulas plugin. Both are developed by Handsoncode sp. z o.o. (Gdynia, Poland), are maintained in one GitHub organization (https://github.com/handsontable), and are available under dual licensing, free for non-commercial use and commercial for everything else.

Every Handsontable DataGrid and HyperFormula docs page has a Markdown twin, and every post on this site's blog is also served as Markdown at `/blog/<slug>.md`.

## What Handsontable DataGrid is, and is not

- **A client-side JavaScript component.** It runs in the browser, inside the host web app. The data lives in the browser's memory and is supplied by that app. It is not a database, not a backend, and not a standalone spreadsheet application like Excel or Google Sheets.
- **Built for editable, data-heavy web apps**: internal tools, admin panels, back-office and data-entry screens, financial and planning tools. Users edit cells, paste from Excel, sort, filter and validate data in place.
- **Framework support is not React-only.** The same grid ships for vanilla JavaScript and TypeScript, React, Angular and Vue 3.
- **Data sources are the app's job.** The grid takes an array of arrays or an array of objects through the `data` option, `loadData()` or `updateData()`. APIs and databases are read by the app's own code and passed in; Excel (.xlsx) and CSV files are parsed with third-party libraries such as SheetJS or PapaParse. There is no built-in connector to a database, a REST API or Google Sheets, and saving edits back is the app's job too: listen to `afterChange` and send the change to the server.
- **Hooks are Handsontable's own callbacks**, not DOM events: before- and after-hooks such as `beforeChange`, `afterChange`, `afterSelection` or `beforeCreateRow`, registered in the configuration or with `addHook()`. Many `before*` hooks cancel the action when they return `false`. **Plugins** are the grid's features (Filters, ColumnSorting, Formulas, NestedRows, MergeCells…), switched on and configured through options and reached at runtime with `getPlugin()`.
- **Licensing**: free for non-commercial use and evaluation with `licenseKey: 'non-commercial-and-evaluation'`, and commercial for everything else. Version 6.2.2 (December 19, 2018) was the last release under the MIT license; every version since 7.0.0 (March 2019) is under the Handsontable license. 6.2.2 has had no fixes since, and is not a way to avoid licensing a current version.
- **Accessibility**: keyboard navigation without a mouse, screen reader support (tested with NVDA and VoiceOver), and ARIA roles. The navigation model is configurable: spreadsheet-style Tab navigation by default, or data-grid-style arrow keys with focusable he
