Building the project in VBA

What follows is a Visual Basic for Applications (VBA) application that defines a subroutine named ReadCSVFile that reads a CSV file containing student names and grades. Let’s break down the code:

1. Sub ReadCSVFile(): This line starts the definition of the ReadCSVFile subroutine. It indicates that it doesn’t return any value.
2. These lines declare several variables used in the subroutine:

      Dim fso As Object
      Dim inputFile As Object
      Dim studentGrades As Object
      Dim line As String
      Dim fields() As String
      Dim studentName As String
      Dim grade As String
      Dim grades() As String
      Dim gradeList As String

   1. fso, inputFile, and studentGrades are declared as generic Object types and will be assigned to specific objects later.
   2. line, fields(), studentName, grade, grades(), and gradeList are declared...
