Auto-generate a Table of Contents in Excel
Here's a cool, handy macro that will auto-generate a Table of Contents for any Excel file.

Steps remains the same as in any macro (Alt F11 to start VBA, Insert module, paste the code, save, File -> Return to Excel, then Alt F8, and Run). That's a mouthful, but you know what to do.

Code: VB

Sub GenerateTableOfContents()

' Does a TOC already exist?
' If Err system variable is > 0, it doesn't
Dim wSheet As Worksheet
On Error Resume Next
Set wSheet = Worksheets("Table of Contents")
If Not Err = 0 Then
  ' The Table of contents doesn't exist. Add it
  Set wSheet = Worksheets.Add(Before:=Worksheets(1))
  wSheet.Name = "TOC"
End If
On Error GoTo 0

' Set up the table of contents page
wSheet.[A2] = "Table of Contents"
With wSheet.[A6]
  .Value = "Subject"
End With
wSheet.[B6] = "Page(s)"
wSheet.Range("A1:B1").ColumnWidth = Array(36, 12)
TableRow = 7
PageCount = 0
displayMessage =
"We'll do a Print Preview for some calculations."
displayMessage = displayMessage&
"Please ‘Close' the window when it appears."
MsgBox displayMessage

' Now loop thru sheets, collecting TOC info
For Each S In Worksheets
  ThisName = S.Name
  HPages = S.HPageBreaks.Count + 1
  VPages = S.VPageBreaks.Count + 1
  ThisPages = HPages * VPages

  ' Enter info about this sheet on TOC
  wSheet.Cells(TableRow, 1).Value = ThisName
  wSheet.Cells(TableRow, 2).NumberFormat = "@"
  If ThisPages = 1 Then
    wSheet.Cells(TableRow, 2).Value =
    PageCount + 1&" "
    wSheet.Cells(TableRow, 2).Value =
    PageCount + 1&" - "&PageCount + ThisPages
  End If
  PageCount = PageCount + ThisPages
  TableRow = TableRow + 1
Next S

End Sub

That's all there is to it! Note that VBA does not allow putting the lines after an equal to sign (" = ") on a separate line, although the above code has them so (only to save formatting.)

Feel free to leave a note if you don't understand some bit of the code and I'll try to explain, though it's quite self-explanatory. The calculation of the number of pages is done through the number of page breaks inside the Print Preview.
