E164 number formatting in Excel

Excel can be a super tool for managing number phone number migrations but if like me you are fed up of seeing the numbers show up like this: OK... then let's change the format of the cell to Text , this fixes it...right? Wrong! Try to do a find and replace on tel: now and you will see it keeps removing the + from the prefix. I found a fix! In the Format Cells window, under Category select General , now in Type, type +# ?/? exactly like this: Apply this to the column or cells you want to have in the E164 format, now even if you don't type the + at the start, it will automatically put it in for you, format looks good and numbers are now correct!
