Too Long; Didn't Read

Non-coders can easily follow instructions and add this script to their projects. CountCheckbox Function goes through the active sheet and counts the number of checked and unchecked boxes among non-empty rows. Just copy the full script from this blog and run in your spreadsheet.

You have checkboxes in your spreadsheet, you’ll like to count them easily. Well, this script I’ll provide will help you with exactly that. Non-coders can easily follow instructions and add this script to their projects.


Namaste! This is Nibesh Khadka. I am a freelancer that develops scripts to automate Google Workspace Apps like Gmail, Google Sheets, Google Docs, etc.

For Non-Coders

If you’re not a coder and don’t wanna be bothered with a tedious explanation then you can just follow these steps:

Open Script Editor


  1. Open Script editor. On your spreadsheet click the extensions tab and open the apps script as shown in the image above.


  2. Remove all the code in code.gs. Then, copy and paste the code from the Full Code section in this blog.


  3. Save and then reload the spreadsheet. Now, reopen the Apps script as instructed in step 1 (Sometimes the script doesn't work without saving and reloading).


    After this, you just have to make a minor edit as instructed below.


Full Code

Here’s the full script for this blog:


// make minor change here.
// insert the number equivalent of your column with checkboxes here inside square boxes, like [1,2]
// for instance 1 for A, 5 for E, and so on.
const checkBoxColNumber = [5, 8];

/**
 * The function creates a custom menu in spreadsheet
 */
function menu() {

  SpreadsheetApp.getUi()
    .createMenu("Count Checkboxes")
    .addItem("Count Checkboxes", "countCheckbox")
    .addToUi();

}

/**
 * OnOpen is resposbile to insert menu to spreadsheet.
 */
function onOpen(e) {
  menu();
}



/**
 * CountCheckbox goes through the active sheet and counts the number of checked and unchecked box among non-empty rows
 */
function countCheckbox() {

  // get sheet and data
  let sheet = SpreadsheetApp.getActiveSheet();
  let data = sheet.getDataRange().getValues();
  // remove first header column
  data.shift();

  // initate counts as zero
  let trueCount = 0;
  let falseCount = 0;

  // value count will be a nested list but as same length as Counting Checkboxes
  let checkBoxColValueCounts = [...checkBoxColNumber];

  // loop through checkBoxColNumber list and data list 
  for (let j = 0; j < checkBoxColNumber.length; j++) {
    for (let i = 0; i < data.length; i++) {
      // [...new Set(data[i])].filter(String) check to get unique value if its either just true or false
      if ([...new Set(data[i])].filter(String)[0] === true || [...new Set(data[i])].filter(String)[0] === false || data[i].join("") === "") { continue; }
      // if values is true push increase true count else false count
      if (data[i][checkBoxColNumber[j] - 1] === true) {
        trueCount += 1;

      } else {
        falseCount += 1;

      }
    }

    // add true and false count as nested list in respective place
    checkBoxColValueCounts[j] = [trueCount, falseCount];
    // reset 
    //console.log(checkBoxColValueCounts)
    trueCount = 0;
    falseCount = 0;
  }

  // create alert string with all info embeded
  let countStatsString = "";
  for (let j = 0; j < checkBoxColValueCounts.length; j++) {
    countStatsString += `\n In the ${checkBoxColNumber[j]} column, There are ${checkBoxColValueCounts[j][0]} boxes checkd and ${checkBoxColValueCounts[j][1]} unchecked boxes among non-empty rows.`
  }
  // alert the result
  SpreadsheetApp.getUi().alert(countStatsString);
}


Using Script in Your Spread Sheet

For this script to work in your spreadsheet you’re gonna have to make a tiny change in code.


// make minor change here.
// insert the number equivalent of your column with checkboxes here inside square boxes, like [1,2]
// for instance 1 for A, 5 for E, and so on.
const checkBoxColNumber = [5, 8];


See this code in the beginning, you’ll have to [5, 8] replace these values with the number equivalent of the letters representing the columns with the checkbox values in your spreadsheet. For instance, 5 for E and 8 for H. If it’s just one column then just insert one value inside the square box without the comma like [5].


Navigating the Menu

After this, you should save the script and reload your spreadsheet you should be able to see the menu in your spreadsheet, with the title “Count Checkboxes“ similar to the image below.


Menu In Spreadsheet



When you run this function you’ll see an alert box with the sum of all checked and unchecked boxes for non-empty rows in your spreadsheet.
