This tutorial is about the steps required to prefix cell entry with zero in excel 2016 & 2013. If you enter a number with leading zero, excel would automatically remove the zero.
In the above sample data, though the phone number was entered as 09238292267, the leading zero has been removed by excel. You can fix this by the following methods.
Just before entering the number, prefix the number with apostrophe to include zero as shown in the below screenshot.
If you have more than one entry that needs to be prefixed with zero then you can change the formatting for those cells to Text instead of adding apostrophes to each cell entry.
Select the Column, navigate to Number section in the Home tab and choose the format as Text.
