My experience covers advanced spreadsheet work for my full-time work. In addition, I have performed advanced contract work using Excel. This work involved taking data from several spreadsheets and combining it into one master spreadsheet. Also, I have created a worksheet that used macros to validate data from several sheets, combine it into one sheet and produce a text output file to submit to the government for a quarterly submittal. I have taught beginning and advanced Excel at the college level for over 15 years.
