node.js - How to create an Excel File with Nodejs?

Question

I am a nodejs programmer . Now I have a table of data that I want to save in Excel File format . How do I go about doing this ?

I found a few Node libraries . But most of them are Excel Parsers rather than Excel Writers .I am using a Linux Server . Hence need something that can run on Linux . Please let me know if there are any helpful libraries that you know of .

Or is there a way I can convert a CSV file to an xls file ( programmatically ) ?

excel4node is a maintained, native Excel file creator built from the official specification. It's similar to, but more maintained than mxexcel-builder mentioned in the other answer.

// Require library
var excel = require('excel4node');

// Create a new instance of a Workbook class
var workbook = new excel.Workbook();

// Add Worksheets to the workbook
var worksheet = workbook.addWorksheet('Sheet 1');
var worksheet2 = workbook.addWorksheet('Sheet 2');

// Create a reusable style
var style = workbook.createStyle({
  font: {
    color: '#FF0800',
    size: 12
  },
  numberFormat: '$#,##0.00; ($#,##0.00); -'
});

// Set value of cell A1 to 100 as a number type styled with paramaters of style
worksheet.cell(1,1).number(100).style(style);

// Set value of cell B1 to 300 as a number type styled with paramaters of style
worksheet.cell(1,2).number(200).style(style);

// Set value of cell C1 to a formula styled with paramaters of style
worksheet.cell(1,3).formula('A1 + B1').style(style);

// Set value of cell A2 to 'string' styled with paramaters of style
worksheet.cell(2,1).string('string').style(style);

// Set value of cell A3 to true as a boolean type styled with paramaters of style but with an adjustment to the font size.
worksheet.cell(3,1).bool(true).style(style).style({font: {size: 14}});

workbook.write('Excel.xlsx');
