Mobile Phone Numbers/ Cell Phones

I am desperate for some help on this one. The problem is now accepting numbers starting with zero but it does involve formatting/ masks.

I have a sheet with many mobile/ cell phone numbers:
07771123456 for example
But I need to change this format to drop the "0" and add the country code "44", so need to automate this somehow with a mask/macro.

07771123456 needs to change to 447771123456 and there is thousand of these so I cant face any more hours of doing it manually, there is a way isnt there? please for my sanity

I use office 2007.

if they are all the same length use in another column
=44&RIGHT(A1,10)
drag down then copy column paste back special values
if different lengths then
=44&MID(A1,2,20)
should cover it

you could use substitute -->=SUBSTITUTE(A1,0,44) <-- A1 is the old 07771123456 would change it to 44777123456. Is that something you could work with?

kh, the SUBSTITUTE would cause issues if a 0 occurs elsewhere

Another variation on the theme might be:

B1: =REPLACE(A1,1,1,44)
assumes left most char is always a 0

ahh! very true thanks for pointing that out.

You could just add a 1 to the SUBSTITUTE as optional 4th parameter though...

yes I just tested it like so--> =SUBSTITUTE(A1,0,44,1)

I'm glad you've resolved but just to clarify:

The REPLACE Worksheet Function as illustrated would only ever replace the first character of the number... if you were running the Edit -> Replace Tool (via Menus) then yes that would replace all 0's.
