Check Workbook Open: Quick Tips to Ensure Accessibility

Determining whether an Excel workbook is open can be essential when working with multiple files, especially to avoid run-time errors in VBA. I often employ a FOR EACH loop to sift through all the open workbooks and compare each one’s name to the one I’m looking for. Sometimes, I simply use a message box to display whether the specific workbook is open. Other times, I might program VBA to output the result directly into a spreadsheet cell, streamlining the process even further.

It’s quite handy to write code that dynamically checks for the status of workbooks. Whether it’s for editing, data analysis or running repeated tasks, knowing the open or closed status helps maintain smooth workflow in Excel. I’ve found that inserting the results of these checks into a cell can also serve as a useful log when dealing with large datasets or collaborative projects where multiple users might be accessing the same files.

Check IF a WORKBOOK is OPEN

When I’m working with Excel, I often create VBA macros to make my tasks more efficient. One common task is to check if a workbook is already open. Here’s a step-by-step approach I use, with a focus on simplicity:

1. Declare Variables: I start by declaring necessary variables. One essential variable is a Workbook object, which I’ll use within a loop. Check out how to declare variables here.

2. Obtain Workbook Name: I use an input box to ask for the workbook’s name from the user. This is the filename I’ll be looking for among the open workbooks.

3. Loop Through Open Workbooks: Next is looping through each Workbook in the Workbooks collection. A For Each loop is ideal for this task.

   	Code Segment	Purpose
   1.	Dim WB As Workbook	Declare a workbook variable
   2.	myWB = InputBox()	Get the workbook name from the user
   3.	For Each WB In Workbooks	Begin the loop to check each open workbook

4. Check and Activate: If I find a match between WB.Name and the input name, I activate that workbook and display a confirmation with a MsgBox. Here’s how I write an IF statement.

5. Notify if Not Found: If no open workbook has the specified name, I show a “Not Found” message upon completing the loop. This ensures the user is aware that the search ended without a match.

6. Exit if Necessary: As I encounter a matching workbook, I use Exit Sub to leave the macro immediately after finding it, which saves time and resources.

Here’s a simplified version of my macro:

Sub vba_check_workbook()
    Dim WB As Workbook
    Dim myWB As String

    myWB = InputBox("Enter the workbook name.")
    For Each WB In Workbooks
        If WB.Name = myWB Then
            WB.Activate
            MsgBox "Workbook Found!"
            Exit Sub
        End If
    Next WB

    MsgBox "Not Found"
End Sub

This kind of VBA procedure is pretty useful when handling multiple workbooks and you want to avoid errors like trying to open an already open workbook or to check for a specific workbook before running certain macros. Remember, VBA is a powerful tool in Excel, and custom functions (or User Defined Functions, UDFs) can greatly enhance your productivity.
