Hello @kartik,
Just create a file with Tabs as delimiters ( similar to CSV but replace comma with Tab ). Save it with extension .XLS . The file can be opened in Excel .
Some code to help --
var fs = require('fs');
var writeStream = fs.createWriteStream("file.xls");
var header="Sl No"+"\t"+" Age"+"\t"+"Name"+"\n";
var row1 = "0"+"\t"+" 21"+"\t"+"Rob"+"\n";
var row2 = "1"+"\t"+" 22"+"\t"+"bob"+"\n";
writeStream.write(header);
writeStream.write(row1);
writeStream.write(row2);
writeStream.close();
This creates the file in XLS file format
Hope it helps!!
Thank You!!
