Batch string concatenation in Excel

Question

I have a couple hundred of cells in Excel I would like to concatenate into a single string. Is there a simpler method of doing this than going through them one by one manual

Answer 1

where the values that you would like to concantenate start in row 2 column 3 of your sheet

Sub GOWN()
roww = 2
Do While cells(roww, 2) <> ""
    aa = cells(roww, 3)
    dd = dd & aa & ","
    roww = roww + 1
Loop
cells(roww + 1, 3) = dd
End Sub
