Programmatic Way to Transfer Google Sheet CSV to Dropbox - csv

Question

I am trying to put a Google Sheet on a trigger every hour or so to export the contents of a sheet and upload them to Dropbox using Google Apps Script. The below code is successfully getting all of the sheets content and creating a new file in Dropbox, however that file is always empty. I think it has to do with how I'm sending the data, right now I think it is just sending the csv data and not the actual file. I have been searching around trying to figure out how to turn this into a file before sending it to Dropbox but I am stuck :/. Do I need to convert this csv content into a file in Google Drive first or is there a way to do it in real time?
function uploadToDropbox() {
try{
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName('sheet5');
var csvFile = convertRangeToCsvFile('testfile.csv', sheet)
var url = "https://content.dropboxapi.com";
var options = {
"hostname": url,
"method": "POST",
"encoding": "utf8",
"followRedirect": true,
"headers": {"Authorization": "Bearer XXXXXXXX",
"Content-Type": "application/octet-stream",
"Dropbox-API-Arg": '{"path": "/testfile.csv","mode": "overwrite","autorename": false,"mute": false,"strict_conflict": false}'
},
'muteHttpExceptions': true,
'body': csvFile
};
var response = UrlFetchApp.fetch(url + "/2/files/upload", options);
var responseCode = response.getResponseCode();
if(responseCode != 200) {throw 'Error: ' + responseCode + " - " + response}
var jsonResponse = JSON.parse(response.getContentText());
} catch(e) {
Logger.log(e)
}
}
function convertRangeToCsvFile(csvFileName, sheet) {
var activeRange = sheet.getDataRange();
try {
var data = activeRange.getValues();
var csvFile = undefined;
if (data.length > 1) {
var csv = "";
for (var row = 0; 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] + "\"";
}
}
if (row < data.length-1) {
csv += data[row].join(",") + "\r\n";
}
else {
csv += data[row];
}
}
csvFile = csv;
}
return csvFile;
}
catch(err) {
Logger.log(err);
}
}

Try this:
function uploadToDropbox() {
var ss=SpreadsheetApp.getActiveSpreadsheet();
var sheet=ss.getSheetByName('sheet5');
var csvFile=DriveApp.getFileById(convertRangeToCsvFile('testfile.csv', sheet));//this is the file now do whatever you want with it. It contains the csv
var url="https://content.dropboxapi.com";
var options={
"hostname": url,
"method": "POST",
"encoding": "utf8",
"followRedirect": true,
"headers": {"Authorization": "Bearer XXXXXXXX",
"Content-Type": "application/octet-stream",
"Dropbox-API-Arg": '{"path": "/testfile.csv","mode": "overwrite","autorename": false,"mute": false,"strict_conflict": false}'
},
'muteHttpExceptions': true,
'body': csvFile
};
var response=UrlFetchApp.fetch(url + "/2/files/upload", options);
var responseCode=response.getResponseCode();
if(responseCode != 200) {throw 'Error: ' + responseCode + " - " + response}
var jsonResponse=JSON.parse(response.getContentText());
}
function convertRangeToCsvFile(csvFileName, sheet) {
var activeRange=sheet.getDataRange();
var data=activeRange.getValues();
if (data.length>1) {
var csv="";
for(var row=0;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] + "\"";
}
}
if (row>data.length-1){csv += data[row].join(",") + "\r\n";
}else {csv += data[row];}
}
var file=DriveApp.getFilesByName('testFiles.csv').next();//assuming its the only one
file.setContent(csv);
}
return file.getId();
}
