Also:
<Tab> in a substitution command means nothing special. It will
actually search for 5 characters, '<' followed by 'T', then 'a', then
'b', and finally '>'. You PROBABLY meant "seach for a literal tab
character" which can be done either by inserting an actual tab
character, or by using the special "\t" atom, i.e., %s/\t/ /g
That said, your first substitute command would probably be better
accomplished with a :retab command anyway.
