In finance, it's very common to have numbers that are text that should have leading zeroes - like account numbers or other types of identifiers.
So for example, let's talk zip codes. Your spreadsheet has decided to make your column of zip codes a number so for the zip "000123", you're seeing just "123". Since all zip codes need to be 5 digits, the formula in a cell would be:
=right("00000"&A1, 5) where A1 contains the zip code "123".
Logically, this formula is taking the right 5 characters of the string "00000123" which would be "00123".
