Surely a sequence analysis tools are the easiest way to do it.
I'd recommend EMBOSS (open source and runs nicely on most platforms - the
"ccp4" of sequence analysis for me at least)

Seqret (SEQuence RETurn) program:
seqret -out test.seq -osformat gcg test.fasta

PS. fasta format needs ">" as a first line with (optional) description in
the input file. And not sure what amino acids "b" and "j" would get
converted to :-)
