One Possible Application: Plotting a pie chart based on income contributions from all your products and services(daily, weekly or monthly), and reviewing the automatically computed percentages/visual pie slices, can give very illuminating insight.
So, (when considering the automation I speak about) do not think about spreadsheet documents containing one or two click_able buttons that allow a user print a page or copy some cells from one sheet to another. Instead, I want you to picture an application(or Entreprise Information System) that customises the appearance of your spreadsheet workspace(to take advantage of maximum screen capital available on your PC), and offers you custom "floating" data entry forms.
At times, they would prefer to click a button that says "Print ABC", or "Print XYZ" report, instead of having to crawl all over the huge spreadsheet(and get "lost" every now and then), to highlight and print different report pages. Using a custom built data entry form to make data entries into 14 different cells in different parts of a table(at the same time/with one click) would, for them, be "heaven" compared to making the entries one at a time.
A person with proven competence in this area CAN become "notorious" for developing spreadsheet applications, which eliminate drudgery from the process of using MS Excel to handle large amounts of data. Typically, work that takes hours or days will suddenly take minutes or seconds to finish.
