How to get a list of values and each the number of rows in a specific column of the resulting data

Hello.

I was wondering how I can get a list of values and each the number of rows in a specific column of the resulting data.
Because I want to make sure that if I use some nodes to transform some columns, the result is correct.
But now the only way I know is to check the “output table” or use “group by” for some columns.

I’d appreciate it if you could tell me a better way.

Thanks.

Hi @hhkim

Did you check the Value Counter and/or Statistics node?

Thank you for your help.

“Value Counter” node is useful to me.
And “Statistics” node seems to work for numeric type columns.

Thanks.
