  • Delimiter − An optional parameter. The parameter, which is used to convert into arrays based on a delimiter.
  • Count − An optional parameter. The number of substrings to be returned, and if specified as -1, then all the substrings are returned.
  • Compare − An optional parameter. This parameter specifies which comparison method is to be used.

Example

Add a button and add the following function.

Private Sub Constant_demo_Click()
   ' Splitting based on delimiter comma '$'
   Dim a as Variant
   Dim b as Variant
   
   a = Split("Red $ Blue $ Yellow","$")
   b = ubound(a)
   
   For i = 0 to b
      msgbox("The value of array in " & i & " is :"  & a(i))
   Next
End Sub

When you execute the above function, it produces the following output.

The value of array in 0 is :Red
