# x-spreadsheet
The `sheet_to_json` utility function generates output arrays suitable for use
with other JS libraries such as data grids for previewing data. With a familiar
UI, [`x-spreadsheet`](https://myliang.github.io/x-spreadsheet/) is an excellent
choice for developers looking for a modern editor.
This demo is available at <https://oss.sheetjs.com/sheetjs/x-spreadsheet.html>
## Obtaining the Library
The [`x-data-spreadsheet` module](http://npm.im/x-data-spreadsheet) includes a
minified script `dist/xspreadsheet.js` that can be directly inserted as a script
tag. The unpkg CDN also exposes the latest version:
```html
<script src="https://unpkg.com/x-data-spreadsheet/dist/xspreadsheet.js"></script>
```
## Previewing Data
The HTML document needs a container element:
```html
<div id="gridctr"></div>
```
Grid initialization is a one-liner:
```js
/* note that the browser build exposes the variable `x` */
var grid = x.spreadsheet(document.getElementById("gridctr"));
```
The following function converts data from SheetJS to x-spreadsheet:
```js
function stox(wb) {
var out = [];
wb.SheetNames.forEach(function(name) {
var o = {name:name, rows:{}};
var ws = wb.Sheets[name];
var aoa = XLSX.utils.sheet_to_json(ws, {raw: false, header:1});
aoa.forEach(function(r, i) {
var cells = {};
r.forEach(function(c, j) { cells[j] = ({ text: c }); });
o.rows[i] = { cells: cells };
})
out.push(o);
});
return out;
}
/* load data */
grid.loadData(stox(workbook_object));
```
## Editing
`x-spreadsheet` handles the entire edit cycle. No intervention is necessary.
## Saving Data
`grid.getData()` returns an object that can be converted back to a worksheet:
```js
function xtos(sdata) {
var out = XLSX.utils.book_new();
sdata.forEach(function(xws) {
var aoa = [[]];
var rowobj = xws.rows;
for(var ri = 0; ri < rowobj.len; ++ri) {
var row = rowobj[ri];
if(!row) continue;
aoa[ri] = [];
Object.keys(row.cells).forEach(function(k) {
var idx = +k;
if(isNaN(idx)) return;
aoa[ri][idx] = row.cells[k].text;
});
}
var ws = XLSX.utils.aoa_to_sheet(aoa);
XLSX.utils.book_append_sheet(out, ws, xws.name);
});
return out;
}
/* build workbook from the grid data */
var new_wb = xtos(xspr.getData());
/* generate download */
XLSX.writeFile(new_wb, "SheetJS.xlsx");
```
## 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).
