In the past I have worked for the Town of Oakville in Ontario working in the finance department working in excel creating financial reports, doing data entry for Snowbird Transportation, and have taken 3 High School courses and 1 University course where we learned the ins and outs of excel and the whole Microsoft Office Suite.
In addition to this, I have lots of experience working with CSV files in python due to my in progress Computer Science Degree, and previously ran a web development & management company as a summer job so I'll have no issues using FTP / Filezilla to retrieve files.
