Day Job = Full-Time Excel Jockey for the finance department in a multi-national company. We run a parallel of all of our financial software (oracle database) in Excel.
Some of my proudest accomplishments are the vlookup tables that have forever replaced my predecessor's pivots. He was always re-creating the wheel when his data changed, but now my data entry page simply has column "A" numbered, and I can vlookup anything that I need over and over... for different time periods, I use an hlookup system that reads different columns.
Also, I've quickly learned that spreadsheets for management use are always to be password protected (because people in our company have a tendancy to key data over my formulas, and then come crying to me when the bottom line dosen't total any more ) .
However, once I've been staring at my spreadsheets for 8-9 hours, there isn't much love for it when I get home. I'd say 90-95% work related.
