Microsoft Excel invert columns order with VBA

You could use this script from previous accepted answer about sorting columns across sheets: Sort excel columns across sheets

First create a new sheet as first in workbook. Then add columns headers with dates in desired order: 27 june... 1 june

Replace number of columns and number of sheets in script

Save a backup before running this macro, no undo.

After rearrangement delete first sheet

Sub ColumnRearrangement()

Dim nextLabel As String
Dim currentLabel As String

Dim TotalPages As Integer
Dim TotalColumns As Integer

TotalPages = 10
TotalColumns = 200

'Insert a blank column in each page
For p = 2 To TotalPages
    Sheets(p).Select
    Columns("A:A").Select
    Selection.Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
    Range("B1").Select
Next

For c = TotalColumns To 1 Step -1

    'Debug.Print "-" & Cells(1, c).Text & "-" & Str(c)
    nextLabel = Cells(1, c).Text
    Sheets(2).Select
    For oldCulumn = 2 To TotalColumns + 1

        'Debug.Print Cells(1, oldCulumn).Text & "-" & Str(oldCulumn)
        currentLabel = Cells(1, oldCulumn).Text

        If currentLabel = nextLabel Then
            'Debug.Print currentLabel & "-" & Str(oldCulumn)
