Append Comma Separated values of One Column

Hi,

This might be simple but a tricky one for me. Also, I had read a lot about transposing data from rows to columns and vice versa, etc., but couldn't find much about this one.

I have data in one column which are column separated.

I want to append all the data one below the other and take the count of which number appeared how many times. I can take the count from Aggregator.

Approach that I followed: AttributeSplitter(list 0-100(since the values can be too many as well)) to disintegrate the values in different columns. But, that leads to a number of columns and appending all the columns and rows in one column becomes the issue.

Any quick solution for this? Thanks!
