XLSX to JSONExcel 2007+ (XLSX)

The modern Excel workbook format.

OOXML-based spreadsheet format introduced with Microsoft Office 2007. TabularJS parses XLSX files natively in the browser and Node.js — no SheetJS, no xlsx dependency.

Feature support

Example

import tabularjs from 'tabularjs';

// Browser
const file = document.querySelector('input[type=file]').files[0];
const result = await tabularjs(file);

console.log(result.worksheets[0].data);
// => [ [ 'Name', 'Age' ], [ 'Alice', 30 ], ... ]

Why TabularJS for Excel 2007+ (XLSX)?

• No external parser dependencies — faster installs, smaller bundles.
• Works identically in Node.js and modern browsers.
• Output is shape-compatible with Jspreadsheet — render parsed data in a live workbook with one call.
