Question

I have a data table in Excel, that is same as:

    A       B
-------------
1. aaa     11
2. bbb     22
3. ccc     #N/A
4. ddd     44

I’ve wrote a VBA function to get value(col B) by key(in col A)
Ex: =getValue(A1)

In this example, if I type =getValue(A3), function is throw #VALUE! error. I was debug and see error at VLOOKUP function. Here is my code:

Public Function getValue(ByVal key As Variant)

    'get value of the cell at column B which has value 'key' at column A on same row
    column2GetValue = 2
    useClosestMatch = False

    'error here if colum2GetValue contain #N/A
    found = Application.WorksheetFunction.VLookup( _
        key, _
        Worksheets(SHEET_CACHE_NAME).Range("A:B"), _
        column2GetValue, _
        useClosestMatch _
    )

    getValue = found
End Function

How to VLOOKUP get #N/A value in VBA?
Thank for your help!

You can handle the error as below.

Although I suggest you look consider using a more versatile Find in place of Application.VLOOKUP

Sub TestMe()
Dim vTest As Variant
vTest = Application.VLookup("TesT", Range("A1:B10"), 2, False)
If IsError(vTest) Then
MsgBox "Not found", vbCritical
Else
MsgBox "value is " & vTest
End If
End Sub
