Finding the Size of Individual Worksheets

by Allen Wyatt
(last updated November 25, 2015)

Maarten wonders if there is a way to find out the size of each worksheet in a workbook. He has a workbook with almost 100 worksheets and he wants to reduce the size of the workbook file. However, he doesn't know which worksheets are the biggest ones in size.

Figuring out the "size" of individual worksheets depends, in large part, on what is meant by "size." Does it mean the number of cells used? The columns and rows used? How much text is stored in the worksheet? The list of metrics could go on and on.

The problem is that questions such as these miss the mark; a worksheet can have many, many items stored on it. For instance, it could contain comments, formulas, text, charts, sound files, and any number of other items. One chart may be larger than another in terms of numbers of cells, but the other could be larger in terms of objects (such as charts or PivotTables).

The only real way to compare relative sizes of worksheets is to save each worksheet out into its own workbook and then examine the size of each resulting workbook. This obviously doesn't answer precisely how large each individual worksheet is because the act of saving a workbook introduces additional overhead into the saved file. However, if each worksheet is saved in the same way, each one will have comparable overhead and thus can be compared to each other to see which is larger.

The following macro adds a worksheet to the current workbook in order to record the sizes of each workbook created. It then steps through each worksheet and saves it into an individual workbook. The size of the workbook is then determined, recorded, and the new workbook deleted.

Sub WorksheetSizes()
    Dim wks As Worksheet
    Dim c As Range
    Dim sFullFile As String
    Dim sReport As String
    Dim sWBName As String

    sReport = "Size Report"
    sWBName = "Erase Me.xls"
    sFullFile = ThisWorkbook.Path & _
      Application.PathSeparator & sWBName

    ' Add new worksheet to record sizes
    On Error Resume Next
    Set wks = Worksheets(sReport)
    If wks Is Nothing Then
        With ThisWorkbook.Worksheets.Add(Before:=Worksheets(1))
            .Name = sReport
            .Range("A1").Value = "Worksheet Name"
            .Range("B1").Value = "Approximate Size"
        End With
    End If
    On Error GoTo 0
    With ThisWorkbook.Worksheets(sReport)
        .Select
        .Range("A1").CurrentRegion.Offset(1, 0).ClearContents
        Set c = .Range("A2")
    End With

    Application.ScreenUpdating = False
    ' Loop through worksheets
    For Each wks In ActiveWorkbook.Worksheets
        If wks.Name <> sReport Then
            wks.Copy
            Application.DisplayAlerts = False
            ActiveWorkbook.SaveAs sFullFile
            ActiveWorkbook.Close SaveChanges:=False
            Application.DisplayAlerts = True
            c.Offset(0, 0).Value = wks.Name
            c.Offset(0, 1).Value = FileLen(sFullFile)
            Set c = c.Offset(1, 0)
            Kill sFullFile
        End If
    Next wks
    Application.ScreenUpdating = True
End Sub

I mentioned this already in my comment of 14 Aug 2014.

The sheet files are called "sheetxx.xml" except when saved as an Excel binary workbook (*.xmlb) then they are called "sheetxx.bin". They always reside in the folder xlworksheets.

If you didn't delete any sheets the name of the files do correspond to the name you see in the VB Editor.


2016-09-02 12:29:08

JDH

You can also rename the workbook with a .zip extension and open it up, then look through the files called "sheetXX.xml" and find big ones. Keep in mind though that the name of this file doesn't correspond to the sheet name you see in the VB Editor. For that, you have to open up the XML file in a text editor and find the "codename=xxx" attribute.

Wonderful.

Our project team have been struggling with a shared 40MB workbook for months now. 5 minutes with this macro and we identified one sheet tab being 22MB. Very impressed.

Thank you thank you thank you!

Very nice!

Worked like a charm.

I'm going to see if I can add hyperlinks within the size sheet for each of the worksheet names.

Still new at VBA so wish me luck.

Thanks again!

I have a similar problem and tried this solution but receive run time 1004 error. Application defined or object defined error.

@Willy Vanhaelen,

To identify which worksheet in My Computer is which, I had to open the .xml file for the worksheet and find this line near the top of the xml code:

<sheetPr codeName = "Sheet7">

In the file I'm working on, my largest worksheet in My Computer is called sheet61.xml, but when I open it, it's VBE code name "Sheet7" as listed above. I checked this against the VBE Project Explorer and some of the data in the .xml and confirmed it's indeed Sheet7, not Sheet61.

@Kevin,

1. The zip worksheet files are named as in the Visual Basic Editor mostly Sheet1, Sheet2 ... This is not necessarly the order as displayed L-R in the viewed workbook.
2. The zip worksheet Sheet1 does not contain general data. Those are stored elswere i.e. in the _rels folder.


2015-11-27 23:54:37

Kevin

@ Willy Vanhaelen
I have followed your .zip method and now seek confirmation of a couple of my assumptions.
1. The zip worksheet file numbers are numbered in the order as displayed L - R in the viewed workbook. i.e. Not the sheet numbers noted in the VBE
2. The system stores a lot of general data in the zip sheet No. 1

Most excellent Willy. At least the original tip brought me here!

@Paul Whitaker - in Computer (Explorer), find the folder and select the file name, click again on the name to edit it. Highlight the .xlsx and change to .zip then press Enter or click away from the file name.


2015-11-25 09:40:43

Paul Whitaker

Hi Willy Vanhaelen.

Apologies for my naivity but how can you change the extension to .zip. I am currently using Office Excel 2007.

Thank you
Paul

@Andy Thompson

You don't need the macros in this tip. See my comment of 14 Aug 2014.


2015-11-02 17:05:34

Andy Thompson

Have tried the above macro using excel 2010 and each time falls over with run time error 1004. "You cannot save this workbook with the same name as another open workbook or add-in. choose a different name, or close the other workbook or add-in before saving."

If I could get it to work it would be a fantastic help to me.

Look forward to your feedback.

Awesome! It truly helps. As anyone else commented I had a problem with hidden worksheets but, after show them, it worked like a charm!
Thanks

dear Willy Vanhaelen 14 Aug 2014, 08:02 ---- this is easy the best paragraph of info I have ever read I have or should I say had, a 40 MB file that was killing me and the team, using your advice I found that the smallest tab on the workbook that nobody even needed was causing 35 m off the problem thanks you clever man!!


2014-09-09 07:42:23

Willy Vanhaelen

I am refering to the method explained in my comment of 14th August


2014-09-08 10:30:43

LMH

Thanks Willy but I dont understand how to get that to work. I've been using the macro and wondered what that unit was in?


2014-09-07 06:10:44

Willy Vanhaelen

In Explorer it's KB as indicated


2014-09-05 11:06:16

LMH

This is amazing thank you so much!!!

When it returns the file size what s the unit? like bytes etc?

Willy:

Thanks for the tip! Amazing what even relatively experienced can learn from forums such as these.


2014-08-14 08:02:47

Willy Vanhaelen

There is no need for these complicated macros.

Since Excel 2007 the workbooks are saved with the extension .xlsx, .xlsm or .xlsb. In fact they are zip files. So change the extension to .zip and open the file. You'll see a number of folders. Open the 'xl' folder and then the 'worksheets' subfolder. There you see a list of all the sheets in the workbook. If you select View|Details you'll see the size of each worksheet.

There are even file managers such as Total Commander who can open your Excel file as a folder without changing the extension.

Fantastic! Helped me find and fix a 10 MB tab full of (formated) blank cells.

This can help if you want to paste it in your personal Macros:

Sub Sizereport(name1 As String)
'este sub pesa cada hoja para detectar cuál es la hoja que le da más tamaño al archivo
Dim wks As Worksheet
Dim c As Range
Dim mat()
Dim sFullFile As String
Dim sReport As String
Dim sWBName As String
sReport = "Size Report"
sWBName = "Erase Me.xls"
sFullFile = ThisWorkbook.Path & _
Application.PathSeparator & sWBName


fila = Workbooks(name).Worksheets.Count
ThisWorkbook.Worksheets(sReport).Activate
Cells.ClearContents
Set c = Range(Cells(1, 1), Cells(fila + 1, 2))
mat = c
mat(1, 1) = "Nombre de la Hoja"
mat(1, 2) = "Tamaño Aproximado (MB)"
Application.ScreenUpdating = False
' Loop through worksheets
For i = 1 To fila
Set wks = ThisWorkbook.Worksheets(i)
If wks.name <> sReport Then
wks.Copy
Application.DisplayAlerts = False
ActiveWorkbook.SaveAs sFullFile
ActiveWorkbook.Close SaveChanges:=False
Application.DisplayAlerts = True
mat(i + 1, 1) = wks.name
mat(i + 1, 2) = FileLen(sFullFile) / 1000000#
Kill sFullFile
End If
Next i
c = mat
Application.ScreenUpdating = True

End Sub

Also worked for me.

Excel Seattle, I fixed this by making all all hidden sheets visible, first. Add this bit of code to the top of Allen's routine.

' First, make all hidden sheets visible, so they can be selected later
For Each wks In ThisWorkbook.Worksheets
wks.Visible = True
Next wks


2013-04-19 18:11:34

Mike R.

Thank you for the VBA code! It worked great


2013-04-08 11:55:40

Excel Seattle

I added this macro to my personal workbook and tried to run on a different file, and it error'ed out saying "Select method of Worksheet class failed."

I then added it to the workbook itself that I was testing, and the error this time said "Method 'Copy' of object_Worksheet' failed.

Any tips on implementing?
