I work in payroll. I've only been there a little over a month. Each month I have to extract reports from the payroll system and download them in Excel and both times I've done this, when I try and sort the staff numbers into numerical order, it doesn't sort them properly unless they're 4 digit numbers. It puts 130 between 1255 and 1355 for example. They are all formatted as numbers. I've tried manually re-typing in the numbers it doesn't like and adding zeros at the beginning. What can I do? I need to be able to do V lookups and pivot tables and there's over 550 rows of data. I need it to be behaving correctly before I start trying to analyse it. Thank you.
