+## Live Demo
+
+:::note
+
+Due to CSS conflicts between the data grid and the documentation generator,
+features like scrolling may not work as expected.
+
+[The linked demo uses a simple HTML page.](pathname:///xspreadsheet/)
+
+:::
+
+```jsx live
+function SheetJSXSpread() {
+  const [url, setUrl] = React.useState("https://sheetjs.com/pres.numbers");
+  const [done, setDone] = React.useState(false);
+  const ref = React.useRef();
+  const set_url = React.useCallback((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:
+
+- [Development Use](https://cdn.sheetjs.com/xspreadsheet/xlsxspread.js)
+- [Production Use](https://cdn.sheetjs.com/xspreadsheet/xlsxspread.min.js)
+
+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:
+
+```js
+(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:
+
+```js
+/* 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:
+
+```html
+<!-- 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:
+
+```html
+<div id="gridctr"></div>
+```
+
+Grid initialization is a one-liner:
+
+```js
+var grid = x_spreadsheet(document.getElementById("gridctr"));
+```
+
+`x-spreadsheet` handles the entire edit cycle. No intervention is necessary.
+
+#### Additional Features
+
+This demo barely scratches the surface.  The underlying grid component includes
+many additional features that work with [SheetJS Pro](https://sheetjs.com/pro).

+been integrated into the ReactJS framework and other foundational JS libraries.
+
+JS Engines have improved over the years, but there are some hard limits to
+browser support using traditional methods of data processing.  Vendors have
+introduced APIs and techniques for representing and processing very large binary
+and textual files. Since many of the techniques only work in a few engines, they
+are recommended only when the traditional approaches falter:
+
+<ul>{useCurrentSidebarCategory().items.map((item, index) => {
+  const listyle = (item.customProps?.icon) ? {
+    listStyleImage: `url("${item.customProps.icon}")`
+  } : {};
+  return (<li style={listyle} {...(item.customProps?.class ? {className: item.customProps.class}: {})}>
+    <a href={item.href}>{item.label}</a>{item.customProps?.summary && (" - " + item.customProps.summary)}
+  </li>);
+})}</ul>
