Hi,
first of all, happy new year!
I understand that working with large amounts of data can take a lot of time and effort, but with a couple of Excel tricks I can get your work done within one day.
I've used Excel and spreadsheets both personally and professionally for many years, so you can trust me for this task! :)
I'm offering a low price because I'm willing to build my reputation in Freelancer, so take this chance for a quick and cheap service!
Looking forward to help you, please feel free to contact me if you have any questions.
