Excel vba if workbook opened

Home / VBA / VBA Check IF a Workbook is Open (Excel File)

To check if a workbook is open using a VBA code, you need to use FOR EACH loop that can loop through all the workbooks that are open at the moment and verify each workbook’s name with the name you have mentioned. You can use a message box to get the result of the loop. Or you can also make the code to enter the result in a cell.

  1. First, you need to declare variables to use in the code to create a loop.
    1-create-a-loop
  2. Use an input box to get the name of the workbook that you wish to search for.
    2-use-an-input-box
  3. Start the loop to loop through all the open workbooks.
    3-start-the-loop-to-loop
  4. Write code with IF STATEMENT to verify the name of the workbook with the name you have entered in the input box, and once the name matches, activates the workbook, show a message box that workbook is found, and exit the procedure.
    4-code-with-if-statement
  5. In the end, end the loop and use a message box to show a message box if nothing has been found.
    5-end-the-loop-and-use-amessage-box

Explanation about how to check if workbook is open

EXPLANATION

EXPLANATION
This tutorial shows how to check if a specific workbook is open in the same Excel session or across all Excel sessions, using VBA.

The first method shows how to check if a workbook, with a specific name, is open in the same Excel session in which the VBA code is run. The second method shows how to check if a specific workbook, including its location and name, is open in all Excel sessions. This is achieved by creating a User Defined Function and then applying this in a macro.

This Excel tutorial explains how to use Workbooks Open Method to open a closed workbook and check if workbook is opened.

In worksheet automation, we may need to programmatically open another workbook to change data based on the active workbook. Workbooks Open Method is very straight forward to use, you just need to specify the file name to open, but there are many other optional parameters you may want to use.

Note that Workbooks Open Method is different from Workbook Open Event, the latter is to trigger VBA when a workbook is opened.

Example of Excel VBA Workbooks Open Method

Assume that you have two workbooks. One is called FileA.xlsm, another is called FileB.xlsx

Now you want to open FileB from FileA, so FileA should contain the Macro (therefore .xlsm) and FileB does not need any Macro.

In FileA, create a Sub in Module and insert the below code, which will open FileB.

Workbooks.Open ("C:UsersWYMANDesktopfolderFileB.xlsx")

After you open FileB, you may need to change the data.  Therefore you need to give FileB a name in order to manipulate it.

The below code give FileB a name called masterWB.

Set masterWB = Workbooks.Open("C:UsersWYMANDesktopfolderFileB.xlsx")

If the FileB is already opened, you will receive an alert.

Now you can manipulate FileA (using thisworkbook) and FileB(using masterWB) from FileA

masterWB.Sheets("Sheet1").Range("A1").Value = "FileB"
ThisWorkbook.Sheets("Sheet1").Range("A1").Value = "FileA"

Check if Workbook is opened already

You may already have FileB opened before the Macro is run, in that case you will receive an alert message if you use Workbooks.Open, this will prevent your Macro from further running.

workbooks_open

There are some methods to test if a Workbook is already opened, below is my preferred method. This Function loop through  all currently opened Workbook to see if there is a Workbook name same as the name provided in the Function argument.

Public Function wIfWbOpen(wbName As String) As Boolean
    Dim oWB As Excel.Workbook
    wIfWbOpen = False
    For Each oWB In Application.Workbooks
        If oWB.Name = wbName Then
            wIfWbOpen = True
            Exit For
        End If
    Next
    Set oWB = Nothing
End Function

Finally use the Function in the Sub in which you want to run code in FileB.

Public Sub updateData()
    If wIfWbOpen("FileB.xlsx") Then
        Set masterWB = Workbooks("FileB.xlsx")
    Else
        Set masterWB = Workbooks.Open("C:UsersWYMANDesktopfolderFileB.xlsx")
    End If
End Sub

VBA Working with Workbooks (The Workbook Object)

In this Article

This guide will introduce you working with the Workbook Object in VBA.

The Workbook Object

First, in order to interact with workbooks in VBA, you must understand the Workbook Object.

With the workbook object, you can reference workbooks by their name like this:

However, this code will only work if the workbook is open. If the workbook is closed, you will need to provide the full workbook path:

Instead of typing out the full path, if your desired workbook is in the same directory as the workbook where your code is stored, you could use this line code to open the workbook:

This makes use of the ThisWorkbook object that we will discuss in the next section.

Workbook Index Number

Last, you can reference workbooks by their “Index Number”. The index number of a workbook corresponds to the order that the workbook was opened (technically its the workbook’s position in the Workbooks Collection).

This is useful if you want to do something like close the first (or last) opened workbook.

Activate Workbook, ActiveWorkbook, and ThisWorkbook

If a workbook is NOT ACTIVE, you can access the Workbook’s objects like this:

However, if the workbook is Active, you can omit the workbook object:

And if you want to interact with the workbook’s active sheet, you can also ommit the sheets object:

Activate Workbook

To activate a workbook, use the Activate Method.

Now you can interact with Book2’s object’s without explicitly stating the workbook name.

ActiveWorkbook

The ActiveWorkbook object always refer to the active workbook. This is useful if you’d like to assign the ActiveWorkbook to a variable to use later.

ThisWorkbook

The ThisWorkbook object always refers to the workbook where the running code is stored. To activate ThisWorkbook, use this line of code:

VBA Coding Made Easy

Stop searching for VBA code online. Learn more about AutoMacro — A VBA Code Builder that allows beginners to code procedures from scratch with minimal coding knowledge and with many time-saving features for all users!

Open Workbook

To open a workbook, use the Open Method:

The newly opened workbook will always become the ActiveWorkbook, allowing you to easily interact with it.

The Open Method has several other arguments, allowing you to open read-only, open a password-protected workbook, and more. It’s covered here in our article about Opening / Closing Workbooks.

Open and Assign to Variable

You can also open a workbook and assign it to a variable at the same time:

Open File Dialog

You can also trigger the Open File Dialog Box like this:

Create New (Add) Workbook

This line of code will create a new workbook:

The new workbook now becomes the ActiveWorkbook, allowing you to interact with it (ex. save the new workbook).

Add New Workbook to Variable

You can also add a new workbook directly to a variable:

Close Workbook

Close & Save

To close a workbook with saving, use the Close Method with SaveChanges set to TRUE:

Close without Save

To close without saving, set SaveChanges equal to FALSE:

Workbook Save As

The SaveAs Method is used to save a workbook as.

To save a workbook with a new name, in the same directory, you can imply use this:

where “new” is the new file name.

To save a workbook in a new directory with a specific file extension, simply specify the new directory and file name:

Other Workbook VBA Examples

Workbook Name

Protect Workbook

To protect the workbook structure from editing, you can use the Protect Method (password optional):

To unprotect a workbook use the UnProtect Method:

Loop Through all Open Workbooks

To loop through all open workbooks:

Workbook Activate Event

You can run some code whenever a specific workbook is opened with the Workbook Open Event.

Place this procedure your workbook’s ThisWorkbook Module:

This procedure will activate Sheet1 every time the workbook is opened.

Opening

Workbooks.Open

FileName — The filename of the workbook to open
UpdateLinks — Specifies how links in the file are updated. 1 user specifies how links will be updated. 2 never update the links. 3 always update the links. If this argument is omitted, the user is (meant to be) prompted to make a choice.
ReadOnly — Opens the file as read-only
Format — If you are opening a text file this specifies the delimiter character. 1 tabs. 2 commas. 3 spaces. 4 semi-colons. 5 nothing. 6 custom character.
Password — The password required to open the workbook.
WriteResPassword — The password required to write to a write-reserved workbook
IgnoreReadOnlyRecommended — Lets you supress the read-only recommended prompt (assuming the workbook was saved with a Read-Only recommendation).
Origin — If you are opening a text file this indicates where is originated.
Delimiter — If you are opening a text file and the ‘Format’ argument is 6 then this is the custom delimiter character.
Editable — If the file is an Excel template, then true opens the specific template for editing. False opens a new workbook based on this template.
Notify — If the file cannot be opened in read/write mode, true will add the file to the file notification list.
Converter — The index of the first file converter to try when opening the file.
AddToMru — Adds the workbook to the list of recently used files.
Local — Saves the file either against the language of VBA or against the language of Excel. True is Excel language, false is VBA language.
CorruptLoad — The first attempt is normal. If Excel stops operating while opening the file, the second attempt is safe load. If Excel stops operating on the second attempt then the next attempt is data recovery.

Opening Workbooks

When a workbook is opened it automatically becomes the active workbook.

Opening

Running a macro automatically when it opens

In the (Microsoft Excel Objects > ThisWorkbook) folder, select Workbook in the top left drop-down and select Open from the top right drop-down.
This event is the default event used when you select «Workbook»

Excel VBA Workbooks.Open Method

This Excel VBA tutorial explains how to use Workbooks.Open Method to open another workbook.

Excel VBA Workbooks.Open Method

Workbooks.Open Method is useful when you try to open another Workbook using VBA. For example, you can open a workbook > format the spreadsheet > close the workbook automatically. There are a lot of rarely used arguments for Workbooks.Open Method. As most of them are self explanatory, I will demonstrate some common uses of the Method.

Syntax of Workbooks.Open Method

Name Required/Optional Data Type Description
FileName Optional Variant String. The file name of the workbook to be opened.
UpdateLinks Optional Variant Specifies the way external references (links) in the file, such as the reference to a range in the Budget.xls workbook in the following formula =SUM([Budget.xls]Annual!C10:C25), are updated. If this argument is omitted, the user is prompted to specify how links will be updated. For more information about the values used by this parameter, see the Remarks section. If Microsoft Excel is opening a file in the WKS, WK1, or WK3 format and the UpdateLinks argument is 0, no charts are created; otherwise Microsoft Excel generates charts from the graphs attached to the file.
ReadOnly Optional Variant True to open the workbook in read-only mode.
Format Optional Variant If Microsoft Excel opens a text file, this argument specifies the delimiter character. If this argument is omitted, the current delimiter is used. For more information about the values used by this parameter, see the Remarks section.
Password Optional Variant A string that contains the password required to open a protected workbook. If this argument is omitted and the workbook requires a password, the user is prompted for the password.
WriteResPassword Optional Variant A string that contains the password required to write to a write-reserved workbook. If this argument is omitted and the workbook requires a password, the user will be prompted for the password.
IgnoreReadOnlyRecommended Optional Variant True to have Microsoft Excel not display the read-only recommended message (if the workbook was saved with the Read-Only Recommended option).
Origin Optional Variant If the file is a text file, this argument indicates where it originated, so that code pages and Carriage Return/Line Feed (CR/LF) can be mapped correctly. Can be one of the following XlPlatform constants: xlMacintosh, xlWindows, or xlMSDOS. If this argument is omitted, the current operating system is used.
Delimiter Optional Variant If the file is a text file and the Format argument is 6, this argument is a string that specifies the character to be used as the delimiter. For example, use Chr(9) for tabs, use “,” for commas, use “;” for semicolons, or use a custom character. Only the first character of the string is used.
Editable Optional Variant If the file is a Microsoft Excel 4.0 add-in, this argument is True to open the add-in so that it is a visible window. If this argument is False or omitted, the add-in is opened as hidden, and it cannot be unhidden. This option does not apply to add-ins created in Microsoft Excel 5.0 or later. If the file is an Excel template, True to open the specified template for editing. False to open a new workbook based on the specified template. The default value is False.
Notify Optional Variant If the file cannot be opened in read/write mode, this argument is True to add the file to the file notification list. Microsoft Excel will open the file as read-only, poll the file notification list, and then notify the user when the file becomes available. If this argument is False or omitted, no notification is requested, and any attempts to open an unavailable file will fail.
Converter Optional Variant The index of the first file converter to try when opening the file. The specified file converter is tried first; if this converter does not recognize the file, all other converters are tried. The converter index consists of the row numbers of the converters returned by the FileConverters property.
AddToMru Optional Variant True to add this workbook to the list of recently used files. The default value is False.
Local Optional Variant True saves files against the language of Microsoft Excel (including control panel settings). False (default) saves files against the language of Visual Basic for Applications (VBA) (which is typically United States English unless the VBA project where Workbooks.Open is run from is an old internationalized XL5/95 VBA project).
CorruptLoad Optional XlCorruptLoad Can be one of the following constants: xlNormalLoad, xlRepairFile and xlExtractData. The default behavior if no value is specified is xlNormalLoad and does not attempt recovery when initiated through the OM.

Example 1 – Open a workbook

The below code opens workbook 1.xls and set the workbook as “wb” so that you can use wb to access other workbook Methods.

Example 2 – Open a workbook with password

There are two kinds of password protection – password to open the workbook, and password to modify the workbook.

In either case, if a workbook is password protected, opening the file will pop up a password box.

You can add the password argument to open the file with password automatically. If you open a non-password protected workbook but you add the password argument, you can still open the workbook.

Lets say you have a workbook 3.xlsx which is non-password protected, using the below code will still be able to open the workbook.

Example 3 – Open a workbook without alert

There are many kinds of alerts that may pop up when you open a workbook, preventing you from running the subsequent procedures. Turn off all alerts ensures you to run all the procedures successfully.

Hi Jill —

I am doing something similar. Here is how I do it:

Workbooks.Open FileName:= _
«file.xls», _
updatelinks:=3, WriteResPassword:=»password»
‘check to see if read only
If ActiveWorkbook.ReadOnly Then
ActiveWorkbook.Saved = True
ActiveWorkbook.Close

This assumes you have passwords on your files. The VBA should open the file and if someone else has it open, it will open as read only. It will see that, then skip save, then close. Let me know if it works for you.

  • #3

Try:

Sub Check_If_Workbook_Open()
Dim wbk As Workbook
For Each wbk In Workbooks
If wbk.Name = «Your Workbook.xls» Then
MsgBox «workbook is open»
End If
Next
End Sub

  • #4

The code I’m writing to manipulate the Excel spreadsheet is in MSAccess, so I tried…

If xl.Application.Workbooks.Name = MyFileName Then
xl.Application.Workbooks(FileName).Close
End If

But I got an error saying «Object doesn’t support this property or method.»

Any ideas?

Jill

  • #5

Good idea, but when I tried…

If xl.Application.Workbooks(FileName).ReadOnly = True Then
xl.Application.Workbooks(FileName).Close End If

But got the error «Subscript out of range» if the file was already closed.

I’ve had this same issue and been working it out for days. FYI to anyone else out there, here is how I solved it:

Code:

TargetWb = "Your Workbook.xls"

For Each Workbook In Workbooks
    If Workbook.FullName = TargetWb Then Workbook.Close (False)
Next Workbook
Workbooks.Open(TargetWb).Activate

Hope this saves somebody the hours of aggravation I spent trying to work out an elegant solution to this.

  • #8

just for completeness, you need not to loop through workbooks to check if it is open

Code:

Sub WBG()
Dim WB As Workbook
On Error Resume Next
    Set WB = Workbooks("Your Workbook.xls")
    If Err Then MsgBox "The workbook is not open"
On Error GoTo 0
End Sub

  • #9

Sometimes I actually have a workbook open in the background while running a macro fetching data from it.
When the workbook is already open, I don’t want to close it. So here’s what I do:

Code:

Sub Fetch_data()
Dim WbOpen As Boolean
Dim Wb2 As Workbook, Sh2 As Worksheet
    
    ' Check if workbook is open
    On Error Resume Next
    Set Wb2 = Workbooks("MyWorkbook.xls")
    On Error GoTo 0
    If Wb2 Is Nothing Then
        ' If workbook was NOT open, we'll open it
        ' We'll use the parameter WbOpen to remember whether the workbook was open or not
        Set Wb2 = Workbooks.Open("C:ExcelMyWorkbook.xls", ReadOnly:=True) ' I prefer readonly when fetching data
        Set Sh2 = Wb2.Sheets("MySheet")
        WbOpen = False
    Else
        ' If the workbook was open, we'll just assign the sheet and WbOpen
        Set Sh2 = Wb2.Sheets("MySheet")
        WbOpen = True
    End If
    
    ' Code here...
    ' ............
    ' Code ended..
    
    ' If the workbook was NOT open, we'll close it
    If WbOpen = False Then Wb2.Close SaveChanges:=False
End Sub

  • #10

Jill this just work fine for me… the error handler is see if it is open it will set work workbook but if not only it is going to go to the workbook is not open

Sub Sample()
Dim BA As Workbook

On Error GoTo Handler
Set BA = Workbooks(«BA.xlsm»)

If BA.Name = «BA.xlsm» Then
MsgBox «Workook is open»
Else
Handler:
MsgBox «Workbook is closed»
End If

End Sub

I’m using Excel 97.

I wrote some VBA code that loops through all of the workbooks in a specified subdirectory and popolates each of them with data from a MS Access 97 database. It works well, but I’m stuck on one thing….

How can I check to see if a specific workbook is currently open (or closed)?

Any help would be greatly appreciated.

Thanks,
Jill

Как проверить открыта ли книга?

Собственно суть темы отражена в названии. Как при выполнении кода из VBA узнать перед обращением к книге открыта она или нет? Ведь если книга закрыта, то обращение к ней вызовет ошибку, а если открывать без проверки — то это может повлечь за собой утерю данных, если предварительно эта книга не была сохранена. Ни один ни второй вариант, естественно, не устраивают. Я покажу два способа проверки через функции. Если функция вернет True — книга открыта, если False — закрыта. Для проверки функций используем проверочную процедуру Check_Open_Book:

Sub Check_Open_Book()
    If IsBookOpen("Книга1.xls") Then
        MsgBox "Книга открыта", vbInformation, "Сообщение"
    Else
        MsgBox "Книга закрыта", vbInformation, "Сообщение"
        'открываем книгу
        Workbooks.Open "C:Книга1.xls"
    End If
End Sub

Данная процедура вызывает функцию IsBookOpen, передавая ей в качестве параметра имя книги, «открытость» которой мы хотим проверить. Я приведу несколько вариантов самой функции IsBookOpen. Во всех вариантах действует один и тот же принцип: код любого из вариантов функции IsBookOpen необходимо скопировать и вставить в стандартный модуль. Модуль должен быть внутри той книги, в кодах которой планируется проверять открыта ли книга. Только тогда IsBookOpen будет доступна для вызова из любого кода этой же книги.
Если вдруг в момент выполнения на строке If IsBookOpen(«Книга1.xls») Then появится ошибка «Sub or function not defined» — значит функция IsBookOpen либо не была скопирована в стандартный модуль, либо она вообще не в стандартном модуле, а в модуле листа, формы или книги.

Вариант 1:

Function IsBookOpen(wbName As String) As Boolean
    Dim wbBook As Workbook
    For Each wbBook In Workbooks
        If wbBook.Name <> ThisWorkbook.Name Then
            If Windows(wbBook.Name).Visible Then
                If wbBook.Name = wbName Then IsBookOpen = True: Exit For
            End If
        End If
    Next wbBook
End Function

Функция просматривает все открытые книги и если находит среди них книгу с указанным именем, то функция возвращает True. Есть небольшая особенность — функция исключает скрытые книги(это либо надстройки, либо PERSONAL.XLS). Так же из просмотра исключена та книга, в которой расположен сам код. Если Вам нужно проверить наличие книги независимо от её видимости, то необходимо просто заменить блок

    If Windows(wbBook.Name).Visible Then
        If wbBook.Name = wbName Then IsBookOpen = True: Exit For
    End If

на одну строку(просто убрать лишнее условие проверки)

    If wbBook.Name = wbName Then IsBookOpen = True: Exit For

Либо можно использовать

Вариант 2:

Function IsBookOpen(wbName As String) As Boolean
    Dim wbBook As Workbook: On Error Resume Next
    Set wbBook = Workbooks(wbName)
    IsBookOpen = Not wbBook Is Nothing
End Function

Данный способ обращается к любой открытой книге, даже если она скрыта как PERSONAL.XLS или надстройка. Однако у данной функции есть недостаток — используется оператор On Error и если в настройках VBA(Tools —Options -вкладка General) установлено Break on All Errors — то этот код не сработает, если книга не открыта — получим ошибку. В то время как Вариант1 с циклом по всем открытым книгам сработает без ошибок.

Вариант 3:

По просьбам читателей решил добавить код, который проверяет открыта ли книга независимо от её месторасположения и используемого приложения Excel. Книга может быть открыта другим пользователем (если книга на сервере), в другом экземпляре Excel или в этом же экземпляре Excel.

Function IsBookOpen(wbFullName As String) As Boolean
    Dim iFF As Integer, retval As Boolean
    iFF = FreeFile
    On Error Resume Next
    Open wbFullName For Random Access Read Write Lock Read Write As #iFF
    retval = (Err.Number <> 0)
    Close #iFF
    IsBookOpen = retval
End Function

Функция несколько отличается от приведенных выше — передается в неё не только имя книги, а полный путь к книге, включая имя и расширение:

Sub Test()
    MsgBox "Файл 'Книга1'" & IIf(IsBookOpen("C:Книга1.xls"), " уже открыт", " не занят")
End Sub

Или более близкий к жизненной ситуации вариант: надо открыть книгу, внести в книгу изменения, сохранить и закрыть. Если книга кем-то уже открыта — получим ошибку на этапе сохранения или запрос на этапе открытия. Поэтому сначала проверяем доступность книги и если она доступна — вносим изменения и сохраняем.

Sub Test()
    Dim sWBFullName As String
    Dim wb As Workbook
    'полный путь к проверяемой книге
    sWBFullName = "C:DocumentsКнига1.xls"
    'если книга кем-то открыта - пропускаем обработку этой книги
    'книга закрыта - вносим изменения, сохраняем, закрываем
    If IsBookOpen(sWBFullName) = False Then
        Set wb = Application.Workbooks.Open(sWBFullName)
        'изменяем значение ячейки "A1" на первом листе книги
        wb.Sheets(1).Range("A1").Value = "www.excel-vba.ru"
        ws.Close True
    End If
End Sub

При использовании функции IsBookOpen так же надо учитывать, что она может посчитать книгу открытой не только если она реально кем-то открыта, а если к ней просто нет доступа(например, заблокирован доступ со стороны администратора и т.п.).

Открыта или закрыта книга Excel? Проверяем с помощью кода VBA по краткому или полному имени файла, используя объектную переменную, цикл или оператор Open.

Проверка по краткому имени

Способ проверки по краткому имени, открыта ли рабочая книга, позволяет определить состояние проверяемой книги в том же экземпляре приложения Excel, в котором открыта книга с проверяющим кодом.

Использование объектной переменной

Вариант пользовательской функция VBA Excel, предназначенной для проверки, открыта или закрыта рабочая книга, путем определения результата присвоения ссылки на нее объектной переменной. Присвоение состоялось (BookOpenClosed = True) – книга открыта, произошла ошибка и присвоение не состоялось (BookOpenClosed = False) – книга закрыта.

Function BookOpenClosed(wbName As String) As Boolean

    Dim myBook As Workbook

    On Error Resume Next

        Set myBook = Workbooks(wbName)

    BookOpenClosed = Not myBook Is Nothing

End Function

Аргумент функции:

  • wbName – краткое имя проверяемой рабочей книги.

Перебор открытых книг циклом

Этот вариант функции BookOpenClosed перебирает с помощью цикла все открытые книги Excel и проверяет их краткие имена на совпадение с кратким именем проверяемой книги. Совпадение найдено (BookOpenClosed = True) – книга открыта, совпадение не найдено (BookOpenClosed = False) – книга закрыта.

Function BookOpenClosed(wbName As String) As Boolean

    Dim myBook As Workbook

    For Each myBook In Workbooks

        If myBook.Name = wbName Then

            BookOpenClosed = True

            Exit For

        End If

    Next

End Function

В коллекцию Workbooks входят и скрытые книги, в том числе Личная книга макросов, и книга с функцией.

Проверка по полному имени

Проверка по полному имени с помощью оператора Open позволяет узнать, открыта ли рабочая книга каким-либо другим процессом: текущим экземпляром Excel, в котором открыта книга с проверяющим кодом, другим экземпляром Excel или сторонним приложением.

Function BookOpenClosed(wbFullName As String) As Boolean

    Dim ff As Integer

    ff = FreeFile

        On Error Resume Next

        Open wbFullName For Random Access Read Write Lock Read Write As #ff

        Close #ff

    BookOpenClosed = (Err.Number <> 0)

End Function

Аргумент функции:

  • wbFullName – полное имя проверяемой рабочей книги.

Эта функция открывает с помощью оператора Open файл проверяемой книги с разрешением чтения и записи (параметр access) и запретом чтения и записи, если этот файл уже открыт другим процессом (параметр lock).

Если файл уже открыт другим процессом, а указанный тип доступа (параметр access) не разрешен (параметр lock), операция открытия завершится с ошибкой, а выражение (Err.Number <> 0) возвратит значение True.

Примеры проверки состояния книги

По краткому имени

Sub Primer1()

    If BookOpenClosed(«Книга1.xlsx») Then

        MsgBox «Книга открыта»

    Else

        MsgBox «Книга закрыта»

    End If

End Sub

По полному имени

Sub Primer2()

    If BookOpenClosed(«C:Папка1Папка2Папка3Книга1.xlsx») Then

        MsgBox «Книга открыта»

    Else

        MsgBox «Книга закрыта»

    End If

End Sub
