Want help to add commas after a text in every cell of Microsoft Excel

[!Jumala!]

I have a list of about 23,000 emails. I need to make an E-mail blast. The only way I know how to do that is by adding a comma at the end of each one. How can I save the hassle of inserting a comma manually into each cell.

In an adjacent helper column (column B), put this in B1 and copydown =A1&",". Then do Copy > PasteSpecial > Values on that column to get rid of the formulas.

Here's a short macro that will do this:

Sub AddComma()
Dim cell As Range
For Each cell In Selection
If cell.Value <> "" Then
cell.Value = cell.Value & ","
Else: cell.Value = cell.Value
End If

Next cell

End Sub

Place the code in a general module.Select the range of cells in question then run the macro.
