Linking numbers or unlinking them? Please help

I have a problem where I have two spreadsheets different files. within them I have one field and they are phone numbers. Spreadsheet 1 has the phone number in the following format

(024) 76222222

Spreadsheet two has it in the following format

02476222222

How can I get either spreadsheet 1 to look like spreadsheet 2 or vice a verse (so basically I want to either add or take away a space between the area code and number)? Is there a simple way of doing this.

Example 1

spreadsheet 1 = (024) 76222222

spreadsheet 2 = (024) 76222222

Thanks for your help.
