You can use a help column with formulas, assume the import starts in A2, in
B2 put (if B2 is taken select column B and do insertcolumn)

=SUBSTITUTE(SUBSTITUTE(A2,"-",".",2),"-","")

copy down as long as needed and the copy and paste special as values over
the old values


finally delete the help column

of course this assumes that there are 2 dashes/hyphens to replace and that
you want to remove the first and replace the second with a period

I have below data in the excel from an import.

001-8420-849900

I want to change into 0018420.849900.

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

Thanks!
