With a familiar UI, x-spreadsheet is an excellent choice for a modern editor.

Click here for a live standalone integration demo.

Live Demo

:::caution pass

Due to CSS conflicts between the data grid and the documentation generator, features like scrolling may not work as expected.

The standalone demo uses a simple HTML page.

:::

function SheetJSXSpread() {
  const [url, setUrl] = React.useState("https://sheetjs.com/pres.numbers");
  const [done, setDone] = React.useState(false);
  const ref = React.useRef(); // ref to DIV container
  const set_url = (evt) => setUrl(evt.target.value);

  return ( <>
    <div height={300} width={300} ref={ref}/>
    {!done && ( <>
      <b>URL: </b><input type="text" value={url} onChange={set_url} size="50"/>
      <br/><button onClick={async() => {
        /* fetch and parse workbook */
        const wb = XLSX.read(await (await fetch(url)).arrayBuffer());
        /* set up grid and load data */
        x_spreadsheet(ref.current).loadData(stox(wb));
        setDone(true);
      }}><b>Fetch!</b></button>
    </> )}
  </> );
}

Integration Library

The integration library can be downloaded from the SheetJS CDN:

When used in a browser tag, it exposes two functions: xtos and stox.

stox(worksheet) returns a data structure suitable for grid.loadData
xtos(data) accepts the result of grid.getData and generates a workbook

Reading Data

The following snippet fetches a spreadsheet and loads the grid:

(async() => {
  const ab = await (await fetch("https://sheetjs.com/pres.numbers")).arrayBuffer();
  grid.loadData(stox(XLSX.read(ab)));
})();

The same pattern can be used in file input elements and other data sources.

Writing Data

The following snippet exports the grid data to a file:

/* build workbook from the grid data */
XLSX.writeFile(xtos(grid.getData()), "SheetJS.xlsx");

Other Details

Obtaining the Library

The x-data-spreadsheet NodeJS packages include a minified script that can be directly inserted as a script tag. The unpkg CDN also serves this script:

<!-- x-spreadsheet stylesheet -->
<link rel="stylesheet" href="https://unpkg.com/x-data-spreadsheet/dist/xspreadsheet.css"/>
<!-- x-spreadsheet library -->
<script src="https://unpkg.com/x-data-spreadsheet/dist/xspreadsheet.js"></script>

Previewing and Editing Data

The HTML document needs a container element:

<div id="gridctr"></div>

Grid initialization is a one-liner:

var grid = x_spreadsheet(document.getElementById("gridctr"));

x-spreadsheet handles the entire edit cycle. No intervention is necessary.

Additional Features

:::tip pass

This demo barely scratches the surface. The underlying grid component includes many additional features that work with SheetJS Pro.
