Pure JavaScript Integration

Built with vanilla JavaScript, Jspreadsheet provides a JavaScript spreadsheet component with zero dependencies and compatibility with any build system or no build system at all. Our JavaScript spreadsheet integrates into your existing applications without framework conflicts or version compatibility issues. Works with React, Vue, Angular, or any JavaScript framework.

Simple JavaScript API for managing JavaScript spreadsheet state, handling events, and controlling features programmatically: Direct DOM manipulation for maximum performance, event-driven architecture for reactivity, a complete API for all operations, and full TypeScript support for type safety.

Performance and Scale

Handle massive datasets confidently with our optimized JavaScript spreadsheet engine. This JavaScript spreadsheet library delivers smooth scrolling and interaction with hundreds of thousands of rows while maintaining optimal browser performance. Virtual rendering, enhanced memory management, and smart caching ensure your JavaScript spreadsheet stays responsive regardless of data size. Built to scale from prototype to enterprise without performance degradation.

500+ Excel-Compatible Formulas

Every formula your users expect, implemented with complete Excel compatibility. From basic arithmetic to advanced statistical functions, financial calculations, and text manipulation. If it works in Excel, it works in your JavaScript spreadsheet. Build sophisticated calculations and business rules directly into your JavaScript spreadsheet without server-side processing.

Excel-Compatible User Experience

Your users already know how to use spreadsheets. Jspreadsheet provides the exact keyboard shortcuts, mouse interactions, copy/paste behavior, and visual feedback that users expect from Excel and Google Sheets, eliminating training time and adoption friction. This familiar interface, combined with pure JavaScript flexibility, creates JavaScript spreadsheet experiences.

Export to / Import from XLSX

Import and export spreadsheets in .XLS and .XLSX formats with full fidelity: all formulas and calculations, cell formatting and styles, charts and embedded objects, multiple worksheets, named ranges and defined names, and data validation rules. Export data, formulas, and styles to XLSX format, ensuring complete compatibility with Excel and other software.

Custom JavaScript Editors

Build your own cell editors using the JavaScript API. Create specialized inputs for your domain-specific data types, integrate with external services, or build complex multi-field editors with full access to the DOM and JavaScript ecosystem. Transform static spreadsheet cells into interactive elements with dropdown lists, date pickers, color pickers, file uploads, and more.

Real-Time Collaboration

Multiple users can edit the same spreadsheet simultaneously with conflict resolution algorithms, user presence indicators, live cursor tracking, automatic change synchronization, and offline editing with sync on reconnect. Advanced permission controls include cell-level permissions, sheet protection, user role management, field-level encryption, and audit logging.

What Our Customers Are Saying

Case studies

"At SplitC we struggled sometimes when users wanted to bulk insert/edit things (sometimes over 100k rows) and we needed performance. Jspreadsheet is probably the fastest spreadsheet component you'll find out there, and with a small bundle size. By the way, support is awesome."

Lucas SegersSplitC

"We vetted 10 JavaScript components and we must say that Jspreadsheet comes out as the best."

Lode CoolsBizzcontrol

"The latest version of Jspreadsheet is a powerful data grid tool, providing an excellent front end for our spreadsheet interface. The Jspreadsheet team is helpful and quick to respond."

JavaScript Spreadsheet for Enterprise Applications

Enterprise teams pick Jspreadsheet when the spreadsheet is the product: financial modeling tools, budgeting and planning apps, quoting engines, and internal tools that replace fragile shared workbooks. Because the core is vanilla JavaScript, the same component runs in a legacy jQuery page, a Vite app, or behind a React, Vue, or Angular wrapper.

Every feature on this page, including the formula engine, XLSX import, and real-time collaboration, is included in a single license. Compare editions on the pricing page or explore the documentation to see the full API.

What Developers Build with This JavaScript Spreadsheet

Common builds on this component, each linked to its documentation.

Spreadsheets with Excel-compatible formulas

Formulas work out of the box: type them in cells or ship them with your data, as in the quickstart above. Calculations run on the client with the same syntax users know from Excel, including cross-worksheet references. The formulas documentation covers custom functions, and Formula Pro adds the complete 500+ function set.

Excel file import and export

Let users drop an XLSX file into your application, edit it, and download the result. Formulas, formatting, merged cells, and multiple worksheets survive the round trip. See import from XLSX and export to XLSX.

Data entry with typed columns

Each column can enforce a type with its own editor: dropdowns, calendars, checkboxes, images, colors, and more. The full list of editors is in the columns documentation.

Reacting to user changes

Every edit fires an event, which makes it straightforward to sync spreadsheet data with your backend, local storage, or a chart library. All events are listed in the events documentation.

Still have questions? Talk to the engineers who build it.

Is there a free JavaScript spreadsheet library?

Yes. Jspreadsheet CE is MIT-licensed and free, including for commercial use. The Pro edition on this page adds XLSX import and export, the 500+ function formula engine, real-time collaboration, and more, with a 30-day free trial and no credit card required.

Does Jspreadsheet require a framework?

No. Jspreadsheet is written in vanilla JavaScript and works with a plain script tag or any bundler. Official wrappers exist for React, Vue, and Angular when you need them.

Can users open and save Excel files?

Yes. XLSX, XLS, and CSV import and export are built in. Formulas, cell formatting, merged cells, and multiple worksheets are preserved in both directions.

How many rows can a JavaScript spreadsheet handle?

Hundreds of thousands of rows. Virtual rendering only draws visible cells, so scrolling and editing stay smooth as data grows.

What is the difference between a JavaScript spreadsheet and a data grid?

A spreadsheet gives users free-form editing with formulas and Excel behavior. A data grid presents structured records with typed columns and validation. Jspreadsheet does both: see the JavaScript data grid page for the data-centric view, or the JavaScript table page for lightweight editable tables.
