In a Range Excel member object, the default is Value
Therefore, SomeVariable = Range("A1") same as SomeVariable = Range("A1").Value
Similarly, Range("A1") = SomeVariable is the same as Range("A1").Value = SomeVariable
Of course, you have to be careful when you say a = Range("Test")
When you try to save a value from a continuous range to a Variant variable, for example, the Test range refers to, say, A1:A10 , then you get an array of values
Sub Sample() Dim Myar Myar = Range("A1:A10").Value Debug.Print UBound(Myar) End Sub
Again, in this case, Myar = Range("A1:A10").Value Myar = Range("A1:A10") is the same as Myar = Range("A1:A10")
If I read / write in a range, when do I just use the name of the range and when do I need to use range.value?
I'm not sure what you mean when do just use the range name but it doesnโt matter if you use .Value or not when you read / write from / to a range. IMHO, this is a good practice to use. .Value :)
Does it matter if the range is a single cell or multiple cells?
No, even then it doesnโt matter if you use. .Value or not.
Does the type of the variable matter?
Oh yeah! See the example array above
Or a data type in a range?
Excel cells can store various types of data. From numbers to dates and strings. Since you do not know what type it is, it is recommended to use Variant when working with them. Here is a classic example
Let's say cell A1 has this number 123456789
Now try this code
Sub Sample() Dim someVariable As Integer someVariable = Range("A1").Value Debug.Print someVariable End Sub
Now try this one
Sub Sample() Dim someVariable As Variant someVariable = Range("A1").Value Debug.Print someVariable End Sub
As Tim Williams noted in the comments
Using .Value also useful for "eliminating the ambiguity of the" general "forgot to use Set when setting an object variable" task - Dim a: Set a = Range("A1") vs Dim a: a = Range("A1") In the second case, always used .Value clarifies the actual problem
