msexcel-builder

A simple and fast library to create MS Office Excel(>2007) xlsx files(Compatible with the OpenOffice document format).

Features:

• Support workbook and multi-worksheets.
• Custom column width and row height, cell range merge.
• Custom cell fill styles(such as background color).
• Custom cell border styles(such as thin,medium).
• Custom cell font styles(such as font-family,bold).
• Custom cell border styles and merge cells.
• Text rotation in cells.

Getting Started

Install it in node.js:

npm install msexcel-builder

var excelbuilder = require('msexcel-builder');

Then create a sample workbook with one sheet and some data.

  // Create a new workbook file in current working-path
  var workbook = excelbuilder.createWorkbook('./', 'sample.xlsx')
  
  // Create a new worksheet with 10 columns and 12 rows
  var sheet1 = workbook.createSheet('sheet1', 10, 12);
  
  // Fill some data
  sheet1.set(1, 1, 'I am title');
  for (var i = 2; i < 5; i++)
    sheet1.set(i, 1, 'test'+i);
  
  // Save it
  workbook.save(function(err){
    if (err)
      throw err;
    else
      console.log('congratulations, your workbook created');
  });

or return a JSZip object that can be used to stream the contents (and even save it to disk):

   workbook.generate(function(err, jszip) {
     if (err)
       throw err;
     else {
       var buffer = jszip.generate({type: "nodebuffer"});
       require('fs').writeFile(workbook.fpath + '/' + workbook.fname, buffer, function (err) {
     }
   });
