if it's always the same number of digits between the dashes, you can use the
=LEFT and =RIGHT functions to split it up and =CONCATENATE it back together
without the dashes then use the find/replace

I want to change into 0018420.849900.

I know how to replace "-" with "." but not sure how to delete one of "."

Thanks!
