# 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).
