A simple node module for exporting a data set to an Excel xlsx file.

Heavily inspired by Node-Excel-Export

Using XLR

Example of a config object to generate a Excel worksheet

{
  name: 'name.xlsx',
  columns: [
    {
      type: 'string',
      width: 10,
    }
  ],
  rows: [],
  merge: []
  stylesXmlFile: 'styles.xml'
}
  • name: Specify worksheet name
  • columns: Array of column definitions
    • type: string / date / bool / number
    • width: (optional) total characters in cell
  • rows: Array of data to be exported. Data needs to be a 2D-Array and should be the same length as the columns array.
  • merge: Array of merge cell objects.
    • row: row index (starting at 1)
    • fromColumn: start the merge from column index (starting at 1)
    • toColumn: end the merge at column index (starting at 1)
  • stylesXmlFile: Absolute path to Excel styles.xml file. An easy way to get a styles.xml file is to unzip an existing xlsx file which has the desired styles and copy the styles.xml file.

Example usage with Express

const express = require('express');
const xlr = require('xlr');
const app = express();

app.get('/', function (req, res) {
  const conf = {
    stylesXmlFile: __dirname + '/styles.xml',
    name: 'report-is-a-thing',
    cols: [
      {
        type: 'string',
        width: 15
      },
      {
        type: 'string',
        width: 25
      },
      {
        type: 'string',
        width: 30
      }
    ],
    rows: [
      [{ value: 'First Name', style: 1 }, { value: 'Last Name', style: 1 }, { value: 'Email', style: 1 }],
      ['Bruce', 'Wayne', 'info@bat.man'],
      ['Clark', 'Kent', 'info@super.man'],
      ['This cell is going to be merged', '', 'test@email.com'],
      ['Peter', 'Parker', 'info@spider.man']
    ],
     merge: [
      { row: 4, fromColumn: 1, toColumn: 2 } 
    ]
  };

  const result = xlr(conf);
  res.setHeader('Content-Type', 'application/vnd.openxmlformats');
  res.setHeader('Content-Disposition', 'attachment; filename=Report.xlsx');
  res.send(new Buffer(result, 'binary'));
});

app.listen(3001, function () {
  console.log('listening on port 3001');
});
