Countif number of characters

Hi all,

I have a column with the len function to determine number of characters in a cell

Can someone advise a formula to count the number of cells in column J with:

1
2
3
4
5 characters and so on?

I am trying and using this but it's hard to manually change the formula.. =COUNTIF(J:J,1) in each cell

TY!

Amazing, TY!
