Edit listbox selected items and save to workbook???

Hello,
You have not mentioned what type of listbox this is, I will assume it is from the controls tool bar, as the code is compatible with a userform
You cannot edit the list box items in the list box, you can select the item and send it to a textbox, in the textbox you can edit, then send it back to your source range, then repopulate the list box.
This is the code you will find in the sheet module.

Private Sub CommandButton1_Click()
    ListBox1.List = Range("A1:A8").Value
End Sub

Private Sub CommandButton2_Click()
    Dim OldS As String, Vl As Range, NewS As String, c As Range
    OldS = ListBox1
    NewS = TextBox1
    Set Vl = Range("A1:A8")
    For Each c In Vl.Cells
        If c = OldS Then c = NewS
    Next c
    ListBox1.List = Range("A1:A8").Value

End Sub

Private Sub ListBox1_Click()
    TextBox1 = ListBox1
End Sub

Click the Populate Listbox button
Select an item from listbox to send it to the textbox
Edit the Textbox item
Click the button to reset the list box.
