How to export google sheet as CSV by selected columns - google-apps-script

Question

I have a Google sheet want to export as CSV file. But there are 2 columns in the sheet I don't want to export.
For example, in the picturecolumn, I don't want to export column "N" and "P"
Here are the Apps Script code I wrote for export
function menu() {
var ui = SpreadsheetApp.getUi();
var menu = ui.createMenu('Menu');
var item = menu.addItem('PICC', 'picc');
var item2 = menu.addItem('Export to CSV', 'csv');
item.addToUi();
item2.addToUi()
};
function onOpen() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var csvMenuEntries = [{name: "Download Primary Time File", functionName: "saveAsCSV"}];
//ss.addMenu("Creating a Timetable", csvMenuEntries);
var ui = SpreadsheetApp.getUi();
var menu = ui.createMenu('Menu');
var item = menu.addItem('PICC', 'picc');
var item2 = menu.addItem('Export to CSV', 'csv');
item.addToUi();
item2.addToUi()
};
function saveAsCSV() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("sheet1");
// create a folder from the name of the spreadsheet
var folder = DriveApp.createFolder(ss.getName().toLowerCase().replace(/ /g,'_') + '_csv_' + new Date().getTime());
// append ".csv" extension to the sheet name
fileName = sheet.getName() + ".csv";
// convert all available sheet data to csv format
var csvFile = convertRangeToCsvFile_(fileName, sheet);
// create a file in the Docs List with the given name and the csv data
var file = folder.createFile(fileName, csvFile);
//File downlaod
var downloadURL = file.getDownloadUrl().slice(0, -8);
showurl(downloadURL);
}
function showurl(downloadURL) {
var app = UiApp.createApplication().setHeight('60').setWidth('150');
//Change what the popup says here
app.setTitle("Your timetable CSV is ready!");
var panel = app.createPopupPanel()
//Change what the download button says here
var link = app.createAnchor('Click here to download', downloadURL);
panel.add(link);
app.add(panel);
var doc = SpreadsheetApp.getActive();
doc.show(app);
}
function convertRangeToCsvFile_(csvFileName, sheet) {
// get available data range in the spreadsheet
var activeRange = sheet.getDataRange();
try {
var data = activeRange.getValues();
var csvFile = undefined;
// loop through the data in the range and build a string with the csv data
if (data.length > 1) {
var csv = "";
for (var row = 1; row < data.length; row++) {
for (var col = 0; col < data[row].length; col++) {
if (data[row][col].toString().indexOf(",") != -1) {
data[row][col] = "\"" + data[row][col] + "\"";
}
}
// join each row's columns
// add a carriage return to end of each row, except for the last one
if (row < data.length-1) {
csv += data[row].join(",") + "\r\n";
}
else {
csv += data[row];
}
}
csvFile = csv;
}
return csvFile;
}
catch(err) {
Logger.log(err);
Browser.msgBox(err);
}
}
As you can see, I used for loop to export the rows and columns, how can I make change to let the two columns not showing in the export CSV

How about this modification?
Modification points :
Modify convertRangeToCsvFile_().
From data retrieved by getValues(), it removes the columns "N" and "P".
In order to reflect this, please modify as follows.
From :
var data = activeRange.getValues();
var csvFile = undefined;
To :
var data = activeRange.getValues();
data = data.map(function(e){return e.filter(function(_, i){return i != 13 && i != 15})}); // Added
var csvFile = undefined;
If I misunderstand your question, please tell me. I would like to modify it.
