Imagine that you have a large file with 20 or more worksheets. It could be, for instance, a file with snapshot financial models for the companies in your coverage universe or a breakdown of home sales in different regions of the city.
You want to sort these worksheets into some kind of order that would allow you and your team to access your data more quickly. The SortSheets
macro will help you to sort your sheet tabs into any kind of order or metric you want (e.g., alphabetically, by ranking, etc.) using the qsort algorithm (an explanation of the algorithm can be found at http://en.wikipedia.org/wiki/Quicksort).
Exhibit 1A: A sample file with multiple worksheets (unsorted)
Exhibit 1B: A sample file with multiple worksheets (sorted)
Exhibit 2: SortSheets macro (VBA)
Sub SwapSheets(S1 As Integer, S2 As Integer)
Dim Sh1 As Worksheet, Sh2 As Worksheet
Set Sh1 = Sheets(S1)
Set Sh2 = Sheets(S2)
Sh1.Move Before:=Sh2
Sh2.Move Before:=Sheets(S1)
End Sub
Function QSortPartitionSheets(L As Integer, R As Integer,
Pvt As Integer) As Integer
Dim PivotValue As String
Dim SI As Integer, I As Integer
PivotValue = Sheets(Pvt).Name
SwapSheets Pvt, R
SI = L
For I = L To R - 1
If Sheets(I).Name <= PivotValue Then
SwapSheets I, SI
SI = SI + 1
End If
Next
SwapSheets SI, R
QSortPartitionSheets = SI
End Function
Sub QSortSheets(L As Integer, R As Integer)
Dim Pvt As Integer
Dim NewPvt As Integer
If R > L Then
NewPvt = QSortPartitionSheets(L, R, L)
QSortSheets L, NewPvt - 1
QSortSheets NewPvt + 1, R
End If
End Sub
Public Sub SortSheets()
QSortSheets 1, Sheets.Count
End Sub
The code in Exhibit 2 allows you to sort your worksheets alphabetically. To sort by some other metric (e.g. ranking, regional sales numbers, etc.), simply change QSortPartitionSheets
to use variants instead of string
s, and define a function to lookup the value using the sheet name (as demonstrated in Exhibit 3).
Exhibit 3: Modified QSortPartitionSheets (VBA)
Function YourFunction(SheetName As String) As Variant
End Function
Function QSortPartitionSheets(L As Integer, R As Integer,
Pvt As Integer) As Integer
Dim PivotValue As Variant
Dim SI As Integer, I As Integer
PivotValue = YourFunction(Sheets(Pvt).Name)
SwapSheets Pvt, R
SI = L
For I = L To R - 1
If YourFunction(Sheets(I).Name) <= PivotValue Then
SwapSheets I, SI
SI = SI + 1
End If
Next
SwapSheets SI, R
QSortPartitionSheets = SI
End Function
