Macro to loop thru sheets adding new columns until it hits particular sheet then stops

[Salts]

Trying to write a macro that will add 2 new columns (A & B) to each sheet in the workbook, adding header names & color coding, but need it to stop when it reaches the tab named "Master"
Below is the code I have so far, but keep getting a compile error in the 'Start loop' section

Sub Insert_Columns()

Dim ws As Worksheet

For Each ws In ActiveWorkbook.Worksheets

On Error Resume Next

'adds new column A & B into each worksheet
ws.[a:b].Insert

'places header in new columns
ws.Range("A1").Value = "Date Deleted: After Master Tab is Created"
ws.Range("B1").Value = "Date Added: After Master Tab is Created"

'Color codes the header "RED" in column A
With ws.Range("A:A").Font
.Color = -16776961
.TintAndShade = 0
.Bold = True
End With

'Color codes the header "Green" in column B
With ws.Range("B:B").Font
.Color = -11489280
.TintAndShade = 0
.Bold = True
End With

With ws.Rows("1:1").EntireRow.AutoFit
End With

'Start loop
For Each sht In ws.Worksheets
'If worksheet in loop is the last one, stop execution (it is Master worksheet)
If sht.Index = ws.Worksheets Then
Exit For
End If

'when loop reaches "Master tab then it stops _
copying tabs to master tab
If sht.Name = "Master" Then
Exit For
End If

Next ws

End Sub

So you just put the

 Name= "Master" Then Exit For [code] at the beginning and don't need the loop thru section.
Sweet.  Appreciate the help.

Want to use this same premise to go back and hide certain column in all worksheets except for "Master" sheet - except when I run the following code - it only works in the "Master" tab, 
it does not hide these columns in any of the other worksheets.

[code]For Each ws In ActiveWorkbook.Worksheets
                
                If ws.Name = "Master" Then Exit For
                
    Range("A:B,D:D,L:L,N:N,Q:S,V:V,Y:Y,AB:AB,AE:AE,AK:AL").Select
    Selection.EntireColumn.Hidden = True
   
    Range("C1").Select
                
            Next ws
    End Sub [end code]
