This is super similar to my start. I was hired at 17 one summer to do data entry for a surveying company, by putting timesheets created in Excel into a central system for billing clients. That got boring after a day, so I figured out how to use VBA (Excel on Macintosh System 8!) and wrote a macro that I linked to a button and put on the spreadsheet template, hidden off in the corner somewhere. When I got the next set of sheets back I hit the buttons and my job was done.
I showed the bosses, and was immediately put to work on some much more interesting stuff linking Lotus Notes with SQL Server for reporting and dashboarding, and then I was off to the races.
(The previous year I'd spent the summer making concrete garden ornaments with a group of ex-cons in a shed in the back of a farm - an experience which certainly made me appreciate the comforts of doing spreadsheets in an air-conditioned office, though my muscles were never quite as good.)
