First part, introduction to algorithms, up to a desired level for data management Second part, application of algorithmic notions for vba applications and to acquire habits to face any situation and be autonomous in language without having to use objects. In this part, parallels can be made with other functional languages where programming languages are applied in a similar way (Python, PHP, Javascript ...) Third part, introduction to the Excel data model (Collections, Objects, Methods). For this part, we forget the algos and we use the objects which reduce the number of lines of code.
