I have two spreadsheets. The first one has a column with numbers in it.
The second one has a column with the same numbers and a description
column as well. Each number can have more than one description. What I
want to do do is iterate the rows in Sheet 1 and lookup the numbers in
sheet 2. Then return all the descriptions to sheet 1 and put them in
the cell next to the number. If there are multiple descriptions for a
number we would like them separated by a comma. Is there a function for
something like this?

TIA

You can use the macro below.

Sub test()

With Sheets("Sheet1")
Sh1RowCount = 1
Do While .Range("A" & Sh1RowCount) < ""
data = .Range("A" & Sh1RowCount)
With Sheets("Sheet2")
Sh2RowCount = 1
Description = ""
Do While .Range("A" & Sh2RowCount) < ""
If .Range("A" & Sh2RowCount) = data Then
If Description = "" Then
Description = .Range("A" & Sh2RowCount)
Else
Description = Description & ", " & .Range("A" & Sh2RowCount)
End If
End If
Sh2RowCount = Sh2RowCount + 1
Loop
End With
.Range("B" & Sh1RowCount) = Description
Sh1RowCount = Sh1RowCount + 1
Loop
End With
End Sub
