The savings _ from using your "in house" expertise _ in terms of money and man_hours alone, will quickly justify the investment you make in "developing the needed skills" _ especially, when you compare what you spend with the cost of purchasing a commercial software application _ or even engaging the services of an Excel VB developer.
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.
Another question I ask, in answering the "Why Excel VB?" question is : "Why re_invent the wheel? ". My experiences(and those of others who favour the use of Excel VB like I do), confirm that to organise, and analyse data for (financial/management) report generation and decision making, you will save hundreds of hours using already in_built, pre_programmed Excel functions compared to a situation where you used Visual Basic proper. All the functions needed to achieve the above purposes already exist in Excel, so that you don't have to write them all from scratch as would be the case if you were to use Visual Basic. 3.It works even when you lack "In House" expertise.
To experience the type of automation I refer to, you can email FREE demos of sample automated Excel VB driven spreadsheet applications like Ƒ) a Training Tracking Database(TM), ƒ) a Fiveƕ) Year Income & Expense Monitor(TM) or Ɠ) an Export Packing List & Invoice Generator(TM) to yourself using the file mailer on my website.
