When formatting a file spaces are added where they shouldn't be added. A couple of examples:
Before a comment block(* bla bla *)
becomes
<space>(* bla bla *)
Before and after ':=' and ':' when they are surrounded by tabs as well as after comments at end of a line
When you have something like this with tabs after the variable, :, type and :=:
VARIABLE_X<tab>: DINT := 0; (* comment *)
becomes
VARIABLE_X<tab><space>: DINT := 0; (* comment *)<space>
