Insert multiple cell values to a comment - excel

Question

I have a task to add a comment in a sumtotal by month to show the items involved and the amount. I Want to simplify the works because Ido it by monthly and every job (over 20 jobs)!
I found solutions for a single cell.
I need to add related cell values to one comment for the month.
Option Explicit
Sub CreateComment()
Dim rng As Range
Dim cel As Range
Dim myColumn, myRow As Integer
Set rng = Selection
myColumn = ActiveCell.Column
myRow = ActiveCell.Row
For Each cel In rng
If cel.Value <> "" Then
Range("myColumn" & "1").AddComment [Cell("myRow", "1")).Value & " -$" & Cell("myRow","myColumn")_.value]
End If
Next
End Sub

Answer 1

Add Comments to a Range
Option Explicit
Sub AddComments()
Dim ws As Worksheet: Set ws = ActiveSheet ' improve!
Dim lRow As Long: lRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row
Dim lCol As Long: lCol = ws.Cells(1, ws.Columns.Count).End(xlToLeft).Column
Dim srg As Range: Set srg = ws.Range("A1").Resize(lRow, lCol)
Dim Data As Variant: Data = srg.Value
Dim r As Long, c As Long, n As Long
Dim Comm As String
For c = 2 To lCol
For r = 4 To lRow
If Len(Data(r, c)) > 0 Then
n = n + 1
Comm = Comm & n & ". " & Data(r, 1) & " - " _
& Format(Data(r, c), "$#,##0") & vbLf
End If
Next r
If n > 0 Then
With srg.Cells(1, c)
.ClearComments
.AddComment Left(Comm, Len(Comm) - 1)
End With
n = 0
Comm = ""
End If
Next c
MsgBox "Comments added.", vbInformation
End Sub
