Clean and reformat telephone numbers in Excel with SUBSTITUTE function To clean up all the phone numbers formatting, the SUBSTITUTE function can help you to replace the unwanted characters (hyphens, periods and parentheses) with empty string. The generic syntax is: =SUBSTITUTE (text, old_text, new_text, [instance_num])
One way to clean up and reformat telephone numbers is to strip out all extraneous characters, then apply Excel’s built-in telephone number format. This formula above uses a series of nested SUBSTITUTE functions to strip out spaces, hyphens, periods, parentheses, and commas. You’ll need to adjust the actual replacements to suit your data.
