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.

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.
