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.
This article is meant for those individuals/businesses who sometimes experience a need to use their spreadsheets in the (somewhat "impersonal"?) manner described above, to get the results they want. That need would often arise out of their lack of requisite skills to get the spreadsheet to behave the way they want _ or limited time to devote towards incorporating necessary automation to make it do so.
Automating Your Spreadsheet Document : What is Excel VB? Microsoft Excel is a powerful tool for recording, organising/re_organising, analysing and presenting information. By Excel VB, I refer to Excel VBA _ where VBA means Visual Basic for Applications(VBA). VBA refers to the highly extensive and flexible macro programming language developed by Microsoft for use in their MS office applications _ Word, Power Point, etc.
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.
