Excel VBA LOOKUP Function
Lookup is the function which helps us to fetch the data from the main table based on a single lookup value. VBA LOOKUP function doesn’t require data structure like that, for LOOKUP function it doesn’t matter whether the result column is to the right or left of the lookup value, still, it can fetch the data comfortably.
This works similarly to the VLOOKUP function but more importantly, this is flexible in a data structure. When we say flexible in the data structure it means VLOOKUP needs all the values to the right of a lookup value in the main table and anything left to the lookup value VLOOKUP cannot find it.
If you already searched for the LOOKUP formula in VBA editor, I am sure you have gone mad because there is a formula called LOOKUP in VBA.
The reason why it is not available by default because LOOKUP is not a VBA function rather it is a worksheet function. So to use the LOOKUP function we need to first make use of the worksheet function in vba class.
- Arg 1 means lookup value
- Arg 2 is our lookup vector i.e. range of our lookup value column
- Arg 3 is our result vector.
How to Use VBA Lookup Function? (Examples)
We have the following data from which we want to get the Avg Price of a particular product name using the Lookup function in VBA Excel.
To get the Avg Price of Mobile Accessories to use the following code.
Step 1: Start the subprocedure in VBA.
Sub Lookup_Example1() End Sub
Step 2: I need the result in F3 cell. So my code is Range(“F3”).Value =.
Sub Lookup_Example1() Range("F3").Value End Sub
Step 3: As I told we cannot straight away access LOOKUP function. So first use the Worksheet Function class.
Step 4: The moment we apply the Worksheet Function class we can see all the available formulas with this class in VBA, so select LOOKUP from this list.
Step 5: With worksheet functions in VBA we don’t see clear arguments of the formula. Here Arg 1 means lookup value. Our lookup value is in the cell E3, so write the code as Range(“E3”).Value.
Sub Lookup_Example1() Range("F3").Value = WorksheetFunction.Lookup(Range("E3").Value End Sub
Step 6: Arg 2 is our lookup vector i.e. range of our lookup value column. In this example, our lookup vector range is from B3 to B10.
Sub Lookup_Example1() Range("F3").Value = WorksheetFunction.Lookup(Range("E3").Value,Range("B3:B10"), End Sub
Step 7: Arg 3 is our result vector. We need the result from the Avg Price column, so the result vector is from Range C3 to C10.
Sub Lookup_Example1() Range("F3").Value = WorksheetFunction.Lookup(Range("E3").Value, Range("B3:B10"), Range("C3:C10")) End Sub
Ok, we are done with the VBA coding.
Let’s run the code and we should get the result in cell F3.
Like this, we can use the LOOKUP function under the worksheet function class to fetch the data of the supplied lookup value.
Use Variables for LOOKUP Function
Using variables also we can arrive results. Below is the example code of lookup function with variables.
Sub Lookup_Example2() Dim ResultCell As Range Dim LookupValueCell As Range Dim LookupVector As Range Dim ResultVector As Range Set ResultCell = Range("F3") Set LookupValueCell = Range("E3") Set LookupVector = Range("B3:B10") Set ResultVector = Range("C3:C10") ResultCell = WorksheetFunction.Lookup(LookupValueCell, LookupVector, ResultVector) End Sub
Even though it looks lengthy it will give good exposure to variables in VBA. Instead of supplying all the values to the formula directly we have declared variables and assigned set of ranges and values to them.
Declaring variables and setting the reference to those variables is always a good practice in any coding language.
Things to Remember
- LOOKUP is an alternative function to VLOOKUP.
- LOOKUP not necessarily requires the result column to be at the right of the lookup value.
- The range length of both the lookup vector and the result vector should be the same.
- More importantly, we need to supply a column index number which is necessary for the VLOOKUP function.
