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
is an excellent
choice for developers looking for a modern editor.
This demo is available at https://oss.sheetjs.com/sheetjs/x-spreadsheet.html
The x-data-spreadsheet
module includes a
minified script dist/xspreadsheet.js
that can be directly inserted as a script
tag. The unpkg CDN also exposes the latest version:
<script src="https://unpkg.com/x-data-spreadsheet/dist/xspreadsheet.js"></script>
The HTML document needs a container element:
<div id="gridctr"></div>
Grid initialization is a one-liner:
/* 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:
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));
x-spreadsheet
handles the entire edit cycle. No intervention is necessary.
grid.getData()
returns an object that can be converted back to a worksheet:
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");
This demo barely scratches the surface. The underlying grid component includes many additional features that work with SheetJS Pro.
