Row Splitter by field length

Does anyone know of a way to split rows by field length. I have a multimillion row table and if a field is more than 20 characters in length, then I want to split them out. Any ideas? Thanks,

I’m not trying to split cells, I am trying to drop rows where the cell is over a certain length

Unless you want to script, use String Manipulation node to add Length column and Row Filter
to drop rows.
