I have tried various solutions to my problem, but none seem to fit my specific requirement. Let me walk you through what I have attempted.
function JSONToCSVConvertor(JSONData, ReportTitle, ShowLabel) {
//If JSONData is not an object then JSON.parse will parse the JSON string in an Object
var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;
var CSV = '';
//Set Report title in first row or line
CSV += ReportTitle + '\r\n\n';
//This condition will generate the Label/Header
if (ShowLabel) {
var row = "";
//This loop will extract the label from 1st index of on array
for (var index in arrData[0]) {
//Now convert each value to string and comma-seprated
row += index + ',';
}
row = row.slice(0, -1);
//append Label row with line break
CSV += row + '\r\n';
}
//1st loop is to extract each row
for (var i = 0; i < arrData.length; i++) {
var row = "";
//2nd loop will extract each column and convert it in string comma-seprated
for (var index in arrData[i]) {
row += '"' + arrData[i][index] + '",';
}
row.slice(0, row.length - 1);
//add a line break after each row
CSV += row + '\r\n';
}
if (CSV == '') {
alert("Invalid data");
return;
}
//Generate a file name
var fileName = "MyReport_";
//this will remove the blank-spaces from the title and replace it with an underscore
fileName += ReportTitle.replace(/ /g,"_");
//Initialize file format you want csv or xls
var uri = 'data:text/csv;charset=utf-8,' + escape(CSV);
// Now the little tricky part.
// you can use either>> window.open(uri);
// but this will not work in some browsers
// or you will not get the correct file extension
//this trick will generate a temp <a /> tag
var link = document.createElement("a");
link.href = uri;
//set the visibility hidden so it will not effect on your web-layout
link.style = "visibility:hidden";
link.download = fileName + ".csv";
//this part will append the anchor tag and remove it after automatic click
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
}
The output I am currently receiving is
CLASSIC_bn_0 CLASSIC_en_0 CLASSIC_en_1 CLASSIC_en_10 CLASSIC_en_11
1 2 28 undefined undefined
1 2 28 undefined undefined
However, I would like the output to be represented column-wise rather than row-wise as follows:
CLASSIC_bn_0 1 1
CLASSIC_en_0 2 2
CLASSIC_en_1 28 28
CLASSIC_en_10 28 28
CLASSIC_en_11 undefined undefined
If anyone has any insights on how to achieve this, I would greatly appreciate your help as I have been stuck on this for quite some time.
Thank you.
