Hi every1!!!

Need to isolate into a different column a value that was found into another
one.
Example:

COL1 COL2
test 123 123

Would like to copy the number part only into another column, using already
existing functions are by means of a custum function

PS. Probably need a custum function, cuz this needs to be applied to 2000+
lines in an excel spreadsheet.

How would i go about this?

Thx for all your hlp!!!!
