List of Job Title Suggestions that Use Excel
Administrative Assistant, Department Assistant, any kind of 'analyst' role (research analyst, etc), job titles with 'research' in them (research assistant) might be appropriate, but you'd have to read the job description, look into positions in accounting (you generally need a 4-year degree to be an accountant, but often there are assistants and administrators in an accounting department), positions with the word 'business' or 'financial' and one of the other words might be appropriate (again, read job description).
If your only experience was just doing work in excel with very little input or intention on your part, it will be difficult to convince someone of your qualifications. Positions that are administrative in nature will generally require good communication skills. Positions that are industry specific they will generally want you to have similar industry experience (financial, healthcare).
