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.
Spreadsheet Automation Facilitates EFFORTLESS Data Handling, Analysis & Report Generation! Sometimes people don't really care about learning(or using) all the "cool' advanced functions, formulas and techniques in the spreadsheet application they use for their work. They just want to punch in their relevant raw data _ at any time _ and immediately see the computed results generated by the spreadsheet in a manner that can facilitate their important decision making.
In addition, visualise it having dynamic query/report drop menu interfaces, and a variety of custom buttons: for navigation(within and between worksheets), printing, data export (as PDF documents or spreadsheet files), saving, auto_data filtering, auto_charts plotting, auto_backup of files, user login authentication (for documents with sensitive or confidential content) etc.
For the purpose of creating custom financial and business management solutions that solve your identified problems, and give you control/ownership, without burning a hole in your pocket, Excel VB offers an amazing variety of possibilities, in the hands of an adequately skilled user.
