=CONCATENATE(A1,",",A2,",",A3) up to A6
Note: if any blank cells you will get extra commas.
e.g. blue,,red,,orange, green if black and purple are missing.
I prefer using a user defined function like the following which ignores blank
cells.
Function ConCatRange(CellBlock As Range) As String
Dim cell As Range
Dim sbuf As String
For Each cell In CellBlock
If Len(cell.text) > 0 Then sbuf = sbuf & cell.text & ","
Next
ConCatRange = Left(sbuf, Len(sbuf) - 1)
End Function
