Can i count the number of repeated items in array column

I have the below lookup column with data array, Can i count how many “C” and how many “D” etc.
Count Reply by Code
Thank you

Steps to reproduce:

  • Create a joined list column from the array, returning it in a form like this: “C, C, C, C, C, C , D, C, C, B, C” (just an example, not the same as your image")

  • Add a JavaScript column and use this code.

let arr = p1.split(", ");
let count = 0;

for (i = 0; i < arr.length; i++) {
if(arr[i] == p2) {
count += 1;

return count;

Then use p1 as the list, p2 as the text you want to count the number of occurrences for.


First of all, Congratulation to the new Professional Title “Certified” you really deserve more.

to be Honest, i would never come up with such solution in my own.
Really thank you


Hola @Hani_Ibrahim

If you want to test another workaround, you can take a look at this 🔢 Count duplicate elements in an array or list

Both solutions work fine, no problem with Thinh’s one.


i will try that too.

Thank you for your continues support.
