Arduino google sheet integration - google-sheets

Question

I'm doing a project with Arduino, I'm trying to post variable's data into google sheet integration but the code doesn't work.
I tried to correct it, but it doesn't post anyway....this is the code.
The error was
ss.sheet.getSheetByName it's not a function
I took the code from Arduino IoT Cloud Google sheet Integration
function myFunction() {
// get sheet named RawData
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Dati");
var MAX_ROWS = 1440; // max number of data rows to display
// 3600s / cloud_int(30s) * num_ore(12h)
var HEADER_ROW = 1; // row index of header
var TIMESTAMP_COL = 1; // column index of the timestamp column
function doPost(e) {
var cloudData = JSON.parse(e.postData.contents); // this is a json object containing all info coming from IoT Cloud
//var webhook_id = cloudData.webhook_id; // really not using these three
//var device_id = cloudData.device_id;
//var thing_id = cloudData.thing_id;
var values = cloudData.values; // this is an array of json objects
// store names and values from the values array
// just for simplicity
var incLength = values.length;
var incNames = [];
var incValues = [];
for (var i = 0; i < incLength; i++) {
incNames[i] = values[i].name;
incValues[i] = values[i].value;
}
// read timestamp of incoming message
var timestamp = values[0].updated_at; // format: yyyy-MM-ddTHH:mm:ss.mmmZ
var date = new Date(Date.parse(timestamp));
/*
This if statement is due to the fact that duplicate messages arrive from the cloud!
If that occurs, the timestamp is not read correctly and date variable gets compromised.
Hence, execute the rest of the script if the year of the date is well defined and it is greater
then 2018 (or any other year before)
*/
if (date.getYear() > 2018) {
// discard all messages that arrive 'late'
if (sheet.getRange(HEADER_ROW+1, 1).getValue() != '') { // for the first time app is run
var now = new Date(); // now
var COMM_TIME = 5; // rough overestimate of communication time between cloud and app
if (now.getTime() - date.getTime() > COMM_TIME * 1000) {
return;
}
}
// this section write property names
sheet.getRange(HEADER_ROW, 1).setValue('timestamp');
for (var i = 0; i < incLength; i++) {
var lastCol = sheet.getLastColumn(); // at the very beginning this should return 1 // second cycle -> it is 2
if (lastCol == 1) {
sheet.getRange(HEADER_ROW, lastCol + 1).setValue(incNames[i]);
} else {
// check if the name is already in header
var found = 0;
for (var col = 2; col <= lastCol; col++) {
if (sheet.getRange(HEADER_ROW, col).getValue() == incNames[i]) {
found = 1;
break;
}
}
if (found == 0) {
sheet.getRange(HEADER_ROW, lastCol+1).setValue(incNames[i]);
}
}
}
// redefine last column and last row since new names could have been added
var lastCol = sheet.getLastColumn();
var lastRow = sheet.getLastRow();
// delete last row to maintain constant the total number of rows
if (lastRow > MAX_ROWS + HEADER_ROW - 1) {
sheet.deleteRow(lastRow);
}
// insert new row after deleting the last one
sheet.insertRowAfter(HEADER_ROW);
// reset style of the new row, otherwise it will inherit the style of the header row
var range = sheet.getRange('A2:Z2');
//range.setBackground('#ffffff');
range.setFontColor('#000000');
range.setFontSize(10);
range.setFontWeight('normal');
// write the timestamp
sheet.getRange(HEADER_ROW+1, TIMESTAMP_COL).setValue(date).setNumberFormat("yyyy-MM-dd HH:mm:ss");
// write values in the respective columns
for (var col = 1+TIMESTAMP_COL; col <= lastCol; col++) {
// first copy previous values
// this is to avoid empty cells if not all properties are updated at the same time
sheet.getRange(HEADER_ROW+1, col).setValue(sheet.getRange(HEADER_ROW+2, col).getValue());
for (var i = 0; i < incLength; i++) {
var currentName = sheet.getRange(HEADER_ROW, col).getValue();
if (currentName == incNames[i]) {
// turn boolean values into 0/1, otherwise google sheets interprets them as labels in the graph
if (incValues[i] == true) {
incValues[i] = 1;
} else if (incValues[i] == false) {
incValues[i] = 0;
}
sheet.getRange(HEADER_ROW+1, col).setValue(incValues[i]);
}
}
}
} // end if (date.getYear() > 2018)
}
}

You are trying to push data directly to the Google sheet on the cloud but it's URL uses https for security reasons. The encryption for https is rather complex and SSL crypto is required. Arduino hardware is normally not fast enough to do SSL. You need more powerful hardware like Raspberry Pi to write directly to the Google Cloud.
However, you can use PushingBox, a cloud that can send notifications based on API calls, to do the hard work for you if you insist on using Arduino ( any variant) in your IOT project. Here you send your data to Pushingbox, it uses http URL, and it will in turn the data to Google sheet.
