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 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 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>

Previewing Data

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));

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:

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.
