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.
I believe using either of these two applications should not pose any problems for implementing your spreadsheet automation ideas. This is because both have always been "friendly", towards making it easy for users to get more functionality out of them by way of custom programming.
The claims I make above are NOT exaggerated. They are in fact based on my personal experiences doing the foregoing (a). As an manager in the challenging, fast_paced manufacturing work environment of a corporate multinational (b). As a solutions developer for individuals and businesses who use MS Excel for their work.
A DIFFERENT Type Of Automation. The approach to spreadsheet automation that I refer to, is one that seeks to provide functional spreadsheet automation alternatives for ANY spreadsheet user task(s). Typically, solutions like this would require the developer to study existing manual data recording, analysis and report generation systems, then plan _ in consultation with users _ for incorporation of automation into the spreadsheet to replace them, where possible.
