Titanium Snippet to Export data to CSV

exportCsvData.js

//Common JS module
exports.exportCsvData = function(input)
{

    var rowTxt = "";
    for(var i=0;i < input.length; i++){ // row iteration
        for(var j = 0; j < input[i].length; j++){ // column iteration
            rowTxt += '"' + input[i][j] + '"';
  
            if(j < (input[i].length-1)) {
                rowTxt += ',';
            }
        }
        rowTxt += '\n';// adding new line at end of row
    }
 
    // creating output file in application data directory
    var outputFile = Ti.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, 'output.csv');
    // writing data in output file 
    outputFile.write(rowTxt); 
 
 
    if (outputFile.exists) {
        alert("CSV generated!!!");
    }
     
    // return output file path
    return outputFile.nativePath;    
}
