JavaScript

Use TabularJS in vanilla JavaScript, no bundler required. Works in any modern browser or Node.js environment with a single function call.

Installation

Install via npm:

npm install tabularjs

Or load directly from a CDN, no build step needed:

<script src="https://cdn.jsdelivr.net/npm/tabularjs/dist/index.js"></script>

Basic Example

Listen for a file input change event and pass the selected file to tabularjs.

import tabularjs from 'tabularjs';

const input = document.getElementById('fileInput');

input.addEventListener('change', async (e) => {
    const file = e.target.files[0];
    if (!file) return;

    const result = await tabularjs(file);
    const [headers, ...rows] = result.worksheets[0].data;

    console.log('Headers:', headers);
    console.log('Rows:', rows);
});

CDN Example

A self-contained HTML page: drop it into any project without a build tool.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8" />
    <title>TabularJS CDN</title>
</head>
<body>
    <input type="file" id="fileInput" />
    <pre id="output"></pre>

    <script src="https://cdn.jsdelivr.net/npm/tabularjs/dist/index.js"></script>
    <script>
    document.getElementById('fileInput')
        .addEventListener('change', async (e) => {
            const file = e.target.files[0];
            if (!file) return;

            const result = await tabularjs(file);
            document.getElementById('output').textContent =
                JSON.stringify(result, null, 2);
        });
    </script>
</body>
</html>

Node.js

Read a file from disk with fs and parse it server-side.

import { readFile } from 'fs/promises';
import tabularjs from 'tabularjs';

const buffer = await readFile('./data.xlsx');
const result = await tabularjs(new Blob([buffer]));

const [headers, ...rows] = result.worksheets[0].data;
console.log('Headers:', headers);
console.log('Rows:', rows);
