Why is it that when a boolean value is logged as a checkbox, it shows up as undefined?

In my code, I'm attempting to log the value of a variable named check, which corresponds to column 11 in a spreadsheet. This variable is meant to represent the state of a checkbox (true or false) based on whether it's been ticked or not. However, when I try to log this value, I keep getting an 'undefined' error message and I'm unsure why.

If anyone could provide some insight into this issue, I would greatly appreciate it. I've included a comment for your reference within the code snippet below.

function sendEmail() {

 // Function setup
 var ActiveSheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
 var StartRow = 2;
 var RowRange = ActiveSheet.getLastRow() - StartRow + 1;
 var WholeRange = ActiveSheet.getRange(StartRow,1,RowRange,11);
 var AllValues = WholeRange.getValues();

 var message = "";
 for (i in AllValues) {

 var CurrentRow = AllValues[i];

 var EmailSent = CurrentRow[13];


// Issue arises here
   var check = CurrentRow[11];
   Logger.log(check)




 if (EmailSent == "sent") 
     continue;

 // HTML template for email content
  message +=
      "<p><b>Timestamp by: </b>" + CurrentRow[1] + "</p>" +
      "<p><b>Requester Email: </b>" + CurrentRow[2] + "</p>" +
      "<p><b>Star Rating: </b>" + CurrentRow[3] + "</p>" +
      "<p><b>Request Category: </b>" + CurrentRow[4] + "</p>" +
      "<p><b>Description: </b>" + CurrentRow[5] + "</p>" +
      "<p><b>Label: </b>" + CurrentRow[6] + "</p>" +
      "<p><b>Ticket ID: </b>" + CurrentRow[7] + "</p>" +
      "<p><b>Comment: </b>" + CurrentRow[8] + "</p>" +
      "<p><b>Status: </b>" + CurrentRow[9] + "</p><br><br>";

  var setRow = parseInt(i) + StartRow;

  ActiveSheet.getRange(setRow, 13).setValue("sent");
}

 var SendTo = "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="32575f535b5e72575f535b5e1c5d40551c5347">[email protected]</a>" + "," + "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="85e0e8e4ece9c5e0e8e4ece9abeaf7e2abe4f0">[email protected]</a>";

 var Subject = "CT IT feedback";


  MailApp.sendEmail({
      to: SendTo,
      cc: "",
      subject: Subject,
      htmlBody: message,
});
}

Answer №1

When extracting values from a sheet, nested for loops are essential to consider. Although unfamiliar with the functions utilized in your code snippet, an example of navigating through a sheet is provided below for educational purposes.

Check out the illustration below.

var sheet = [
    [1,2,3,4],
    [5,6,7,8],
    [9,10,11,12]
];

// Visualize the array above as a representation of your sheet.
// Moving across 1, 2, 3, 4 and then down to the next row
// 5, 6, 7, 8 and so forth.

var rows = sheet.length;
var rowCount;

for(var i = 0; i < rows; i++) {
    rowCount = 0;
    for(var j = 0; j < sheet[i].length; j++) {
        rowCount += sheet[i][j];
    }
    // Completed calculation for the row.
    console.log(rowCount);
}

Answer №2

Initially, the for...in statement is designed for iterating through an object's properties, not arrays. It would be more appropriate to utilize the forEach method instead. Consider replacing your current code with the following:

 AllValues.forEach(function(CurrentRow) {

    // Code within loop

})

In addition, the variable CurrentRow is limited to index 10, making it unable to access values at CurrentRow[11] and CurrentRow[13]. To address this issue when defining WholeRange, ensure that you allocate space for at least 14 columns:

var WholeRange = ActiveSheet.getRange(StartRow, 1, RowRange, 14);

I trust that this information proves beneficial!
