renaming field details

[tezdread]

hi all,

i would like to know if it's possible to copy and rename the contents of a field?

e.g. A1 contains "Paul Smith" and I would like B1 to contain "paul_smith.txt"

so all the contents of the one column are copied and renamed so all the letters are lower case and the spaces are changed to underscores and they're suffixed by the .txt

thanks if anyone can help me do this

It can be done with a formula

For multiple spaces use
=LOWER(SUBSTITUTE(SUBSTITUTE(A1,".","")," ","_"))&".txt"

for a single space use

=LOWER(SUBSTITUTE(A1," ","_",1))&".txt"
