# SheetJS CE
SheetJS Community Edition offers battle-tested open-source solutions for
extracting useful data from almost any complex spreadsheet and generating new
spreadsheets that will work with legacy and modern software alike.
[SheetJS Pro](https://sheetjs.com/pro) offers solutions beyond data processing:
Edit complex templates with ease; let out your inner Picasso with styling; make
custom sheets with images/graphs/PivotTables; evaluate formula expressions and
port calculations to web apps; automate common spreadsheet tasks, and much more!
## Simple Examples
The code editors are live -- feel free to edit! They use ReactJS components and
run entirely in the web browser.
### Export an HTML Table to Excel XLSX
<details>
<summary><b>How to add to your site</b> (click to show)</summary>
<Tabs groupId="deployment">
<TabItem value="vanilla" label="HTML">
1) Make sure your table has an ID:
```html
<table id="TableToExport">
```
2) Include a reference to the SheetJS library in your page:
<CodeBlock language="html">{`\
<script src="https://cdn.sheetjs.com/xlsx-${current}/package/dist/xlsx.full.min.js"></script>`}
</CodeBlock>
3) Add a button that users will click to generate an export
```html
<button id="sheetjsexport"><b>Export as XLSX</b></button>
```
4) Add an event handler for the `click` event to export table data to XLSX:
```html
<script>
document.getElementById("sheetjsexport").addEventListener('click', function() {
/* Create worksheet from HTML DOM TABLE */
var wb = XLSX.utils.table_to_book(document.getElementById("TableToExport"));
/* Export to file (start a download) */
XLSX.writeFile(wb, "SheetJSTable.xlsx");
});
</script>
```
</TabItem>
<TabItem value="react" label="React">
:::note pass
This example assumes you have an existing project with an HTML TABLE element:
```jsx title="Sample Component"
function App() {
return ( <>
<h3>SheetJS Table</h3>
<table>
<tr><td colSpan="3">SheetJS Table Export</td></tr>
<tr><td>Author</td><td>ID</td><td>你好!</td></tr>
<tr><td>SheetJS</td><td>7262</td><td>வணக்கம்!</td></tr>
<tr><td colSpan="3">
<a href="//sheetjs.com">Powered by SheetJS</a>
</td></tr>
</table>
</> )
}
export default App;
```
If you are starting from scratch, create a new ViteJS + ReactJS project:
```bash
npm create vite@latest -- sheetjs-react --template react --default
cd sheetjs-react
npm install
npm run dev
```
Replace `src/App.jsx` with the sample component.
:::
1) Install the SheetJS library using a package manager:
<Tabs groupId="pm">
<TabItem value="npm" label="npm">
<CodeBlock language="bash">{`\
npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
</CodeBlock>
</TabItem>
<TabItem value="pnpm" label="pnpm">
<CodeBlock language="bash">{`\
pnpm install --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
</CodeBlock>
</TabItem>
<TabItem value="yarn" label="Yarn" default>
<CodeBlock language="bash">{`\
yarn add https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`}
</CodeBlock>
</TabItem>
</Tabs>
2) Ensure that your component script imports `useRef` from the `react` library:
```js
import { useRef } from "react";
```
3) Add the following line at the top of your component script:
```js
import { utils, writeFileXLSX } from "xlsx";
```
4) Create a ref in the body of your function component:
```jsx
function App() {
// highlight-next-line
const tbl = useRef(null);
// ...
```
5) Attach the ref to the table element:
```jsx
function App() {
// ...
return (
{/*...*/}
// highlight-next-line
<table ref={tbl}>
{/*...*/}
```
6) Add a button with a click handler that will export table data to XLSX:
```jsx
function App() {
// ...
return (
{/*...*/}
// highlight-start
<button onClick={() => {
// generate workbook from table element
const wb = utils.table_to_book(tbl.current);
// write to XLSX
writeFileXLSX(wb, "SheetJSReactExport.xlsx");
}}>Export XLSX</button>
// highlight-end
{/*...*/}
```
</TabItem>
</Tabs>

This example uses a ReactJS `ref` to reference the HTML TABLE element. ReactJS
details are covered in the [ReactJS demo](/docs/demos/frontend/react#html)
```jsx live
/* The live editor requires this function wrapper */
function Table2XLSX(props) {

const tbl = React.useRef();
/* Callback invoked when the button is clicked */
const xport = React.useCallback(() => {
/* Create worksheet from HTML DOM TABLE */
const wb = XLSX.utils.table_to_book(tbl.current);
/* Export to file (start a download) */
XLSX.writeFile(wb, "SheetJSTable.xlsx");
});
return ( <>
<table ref={tbl}><tbody>

<summary><b>How to add to your site</b> (click to show)</summary>
1) Create a container DIV for the table:
```html
<div id="TableContainer"></div>
```
2) Include a reference to the SheetJS library in your page:
<CodeBlock language="html">{`\
<script src="https://cdn.sheetjs.com/xlsx-${current}/package/dist/xlsx.full.min.js"></script>`}
</CodeBlock>
3) Add a script block to download and update the page:
```html
<script>
(async() => {
/* replace with the URL of the file */
const URL_TO_DOWNLOAD = "https://docs.sheetjs.com/pres.numbers";
const ab = await (await fetch(URL_TO_DOWNLOAD)).arrayBuffer();
/* Parse file and get first worksheet */
const wb = XLSX.read(ab);
const wsname = wb.SheetNames[0];
const ws = wb.Sheets[wsname];
/* Generate HTML */
var output = document.getElementById("TableContainer");
output.innerHTML = XLSX.utils.sheet_to_html(ws);
})();

This example starts from a CSV string. Use the File Input element to select
a workbook to load. Use the "Export XLSX" button to write the table to XLSX.
```jsx live
/* The live editor requires this function wrapper */
function Tabeller(props) {
const [__html, setHTML] = React.useState("");
/* Load sample data once */
React.useEffect(() => {
/* Starting CSV data -- change data here */
const csv = `\
This,is,a,Test
வணக்கம்,สวัสดี,你好,가지마
1,2,3,4`;
/* Parse CSV into a workbook object */
const wb = XLSX.read(csv, {type: "string"});
/* Get the worksheet (default name "Sheet1") */
const ws = wb.Sheets.Sheet1;
/* Create HTML table */
setHTML(XLSX.utils.sheet_to_html(ws, { id: "tabeller" }));
}, []);
return ( <>
{/* Import Button */}
<input type="file" onChange={async(e) => {
/* get data as an ArrayBuffer */
const file = e.target.files[0];
const data = await file.arrayBuffer();
