I am keen to encourage individuals and organisations to explore using advanced MS Excel formulas and functions, in conjunction with Excel VBA programming, to develop customised spreadsheet applications that will solve typical problems end_users encounter daily in trying to record/analyse data and generate reports.
From this point on, I will refer to only one of the above mentioned applications, because it is my preferred work environment. That is Microsoft Excel. I believe users of other spreadsheet applications will be able to adapt whatever I say from here for use in their own peculiar environments.
Why Excel Visual Basic _ and NOT Visual Basic? I always answer this question by asking the following question: What would be the point of "Killing A Fly With A Hammer"? Let me elaborate. If a method is available that allows us to achieve the same desired result(s) at LOWER cost, with LESS effort and in LESS time, why should we fail to adopt it? Certain IT persons insist that developing executable applications using the standalone Visual Basic programming language is "better" as it does not limit the user to a particular user application software environment. I concede that this might be a valid point under certain conditions. However, I point out that there are many users who have peculiar needs that do not necessarily require complex solutions. A lot of people today simply want to get their data recording, (re)organisation, and analysis for decision making done quicker and with less effort. They also want to spend as little money as possible to do this. In other words, they want a cost_effective solution that gives them independence from the solution provider in the long term _ without requiring them to undertake laborious skills acquisition immediately. This category of everyday users of technology described above are the ones I believe need Excel VB solutions of the type I describe. One expects that some of these users will over time develop an interest in acquiring advanced skills needed to develop their own solutions in future _ which is why I also encourage them to do so, possibly via self_tutoring, like I did.
You can choose to learn how to do it yourself _ or call in someone(an Excel VB Solutions Developer for instance) who knows how. Again, this would be dependent on your purpose, how proficient you are, and/or how much time you have at your disposal. Ultimately, even if someone develops a custom application for you, it should happen with YOUR guidance at every point to ensure that it does EXACTLY what you want it to do, and that you can easily _ with your developer's support/coaching _ learn how to make modifications to it in future, without needing to call back your developer.
