That's wrong. If the source hot is already in the receptacle box then the
conversion

is fairly simple. You only need to run another wire if the source hot is in
the switch

box.

DerbyDad, as usual, is 100% right. He answered the OP's question correctly
and even supplied the diagrams. If the OP has a receptacle where it's
wired with the power source going to the receptacle first, then to the
switch, then no additional wire needs to be run. The diagram showed
exactly that. It's only if the power goes to the switch first that an
additional wire is needed. Around here at least, that is the most common
configuration. We don't know how it was wired in the OP's case, he
did not say., but given that the OP says he's got it done already,
I suspect he in fact didn't have to run a new cable, so it sounds like
he probably had a hot at the receptacle.
