Question

How to concatenate columns without looping

Asked by: wipnav

I have two columns of data that I need to concatenate. I would like to use code such as this:

LookupSht.Range("C7:C" & LastRow) = LookupSht.Range("A7:A" & LastRow).Value & _
LookupSht.Range("B7:B" & LastRow).Value

But I get an error number 31 'Type mismatch'

Unfortunately I have around 30,000 rows so I cannot loop through each cell and concatenate them together. Any ideas on how to concatenate a range with another range at once?

Thanks for your help!

How about something like this macro (you will get your contents dynamically built with formula):

    ActiveCell.FormulaR1C1 = "=RC[1]&RC[2]"
    Range("A7").Select

You could use:

LookupSht.Range("C7:C" & LastRow).Value = Evaluate("IF(ROW(7:" & LastRow & "),A7:A" & LastRow & "&B7:B" & LastRow & ")")
