At my current full time job, I need Excel every day. I'm creating and maintaining different types of spreadsheets (i.e. monthly sales, commission reports, broken devices / complaint reports).
Also I started a small side business (selling hand tools of a specific company). For that reason I also had to do some researching incl. possible customers, their addresses, contacts (phone, fax, email) and of course the contact for my purposes.
I'm the person to help you with your issue.
I'm looking forward hearing from you
