google app script export csv with semicolon instead of comma - google-apps-script

Question

I am using the code below to export a google spreadsheet to CSV in a specific folder.
I need to have a semicolon (;) as delimiter instead of a comma (,)
function saveAsCSV() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var ssname = ss.getName();
var sheet = ss.getActiveSheet();
var parentFolder = DriveApp.getFolderById("MyID");
var folder = parentFolder;
var curDate = Utilities.formatDate(new Date(), "GMT+1", "yyyyMMdd")
var fileName = "MyName" + curDate + ".csv";
var url = "https://docs.google.com/spreadsheets/d/" + ss.getId() + "/export?
exportFormat=csv&format=csv";
var token = ScriptApp.getOAuthToken();
var response = UrlFetchApp.fetch(url + sheet.getSheetId(), {
headers: {
'Authorization': 'Bearer ' + token
}
});
folder.createFile(response.getBlob().setName(fileName));
}
Thank you for your help

Answer 1

You want to replace , to ; for the retrieved CSV data.
You want to create the replaced data as a file.
If my understanding is correct, how about this answer? Please think of this as just one of several possible answers.
Modification points:
The data that ; is used as the delimiter instead of , is no mimeType of text/csv. In this case, it is required to be text/plain.
In your script, I would like to propose the following 2 patterns.
Pattern 1:
In this pattern, the values are retrieved and the data separated by ; is created.
Modified script:
When your script is modified please modify as follows.
From:
var url = "https://docs.google.com/spreadsheets/d/" + ss.getId() + "/export?
exportFormat=csv&format=csv";
var token = ScriptApp.getOAuthToken();
var response = UrlFetchApp.fetch(url + sheet.getSheetId(), {
headers: {
'Authorization': 'Bearer ' + token
}
});
folder.createFile(response.getBlob().setName(fileName));
To:
var values = sheet.getDataRange().getValues();
var outputData = values.map(r => r.join(";")).join("\n");
folder.createFile(fileName, outputData, MimeType.PLAIN_TEXT);
Pattern 2:
In this pattern, the retrieved CSV data is converted.
Modified script:
When your script is modified please modify as follows.
From:
folder.createFile(response.getBlob().setName(fileName));
To:
var csvData = Utilities.parseCsv(response.getBlob().getDataAsString());
var outputData = csvData.map(r => r.join(";")).join("\n");
folder.createFile(fileName, outputData, MimeType.PLAIN_TEXT);
Note:
Please enable V8.
Reference:
createFile(name, content, mimeType)
If I misunderstood your question and this was not the direction you want, I apologize.
