Excel VBA Debug.Print
Debug Print is one of the useful tools presented in the VBA editorVBA EditorThe Visual Basic for Applications Editor is a scripting interface. These scripts are primarily responsible for the creation and execution of macros in Microsoft software. to figure out how a program is working, and it helps to analyze the changes in the values of variables created in the VBA program. It shows the output of the prompt window when we run the program without any bugs.
Debug.print offers the two main benefits over the use of Msgbox to display the output of the code. It eliminates the need for clicking the OK button every time and shows the log of returned output values to the immediate windows. It saves a lot of time for users. The present article explains the use of excelUse Of ExcelIn today's corporate working and data management process, Microsoft Excel is a powerful tool." Every employee is required to have this expertise. The primary uses of Excel are as follows: Data Analysis and Interpretation, Data Organizing and Restructuring, Data Filtering, Goal Seek Analysis, Interactive Charts and Graphs. VBA Debug Print with many examples and explaining how to use it covering the following things.
What is VBA Debug Print?
Debug is an object in VBA and used with the two methods called Assert and Print. The print is helpful in-display messages and asserts in useful in the evaluation of the conditions. In VBA, debug. The print statement is used in any place of the coding program to show the values of a variable or messages in the Immediate Window. These do not need any acknowledgment or confirmation and do not display any effect on the code developed. It is safe and best to use in the code in the situation to facilitating access to many users. These are just helpful in testing or evaluation of the code to confirm that it is working correctly or not. It prints the variables, strings, numbers, array, values in excel sheets, and empty and active sheets.
How to Use Excel VBA Debug Print?
VBA debug.print is the statement helpful in displaying more variables at a time in the immediate window. It is the best and alternative approach to show the output.
Debug.print count, sum, average, standard deviation
As shown in the example, all the variables are separated with commas. This statement can transfer the output to the immediate window even if a window is not opened. It does not stop running the code as in Msgbox. This flexibility supports continuous monitoring of the changes in the output concerning changes in the code.
The variables count, sum, average, and standard deviation are displayed in the same line with equal space among them. If Immediate Window is not opened, follow the following steps to see the output.
Steps to Open Immediate Window and See the Output
- Press Ctrl + G or click on the ‘View’ menu in the VBA editor.
- Choose the option ‘Immediate Window’.
- Place the cursor in the Window and again run the code.
- Observe the output in the window.
Examples of Excel VBA Debug.Print
The following are the examples to demonstrate the use of debug print in excel VBA.
Example #1 – Displaying the Values of the Variables
First, go to the Developer tabDeveloper TabEnabling the developer tab in excel can help the user perform various functions for VBA, Macros and Add-ins like importing and exporting XML, designing forms, etc. This tab is disabled by default on excel; thus, the user needs to enable it first from the options menu., click on Macros, and create a macro to write the code in the VBA and add a name to it.
After adding a name, click on create. This opens the VBA editor.
Develop a small program, as shown in the figure.
Sub Variables() Dim X As Integer Dim Y As String Dim Z As Double X = 5 Y = "John" Z = 105.632 Debug.Print X Debug.Print Y Debug.Print Z End Sub
As shown in the screenshot, three dimensions or variables are decreased as X, Y, and Z as an integer, string, and Double, respectively. To print these values, Debug.print is used, and the output will be displayed in the prompt window. Press CTRL+G to see the result, as shown in the screenshot.
Run this code using the F5 key and press CTRL+G to see the output in Immediate Window.
This program can be simplified by separating the debug—print statements by a comma.
Sub Variables() Dim X As Integer Dim Y As String Dim Z As Double X = 5 Y = "John" Z = 105.632 Debug.Print X, Y, Z End Sub
This debugs statement prints the output in the same line, as shown in the screenshot.
Example #2 – Debug print to File
This example illustrates the use of VBA debug print to display output to a file when the length of the text is too high.
The program to print the output on a file is developed, as shown in the figure.
Sub DebugPrintToFile() Dim s As String Dim num As Integer num = FreeFile() Open "D:ArticlesExceltest.txt" For Output As #num s = "Hello, world!" Debug.Print s ' write to the immediate window Print #num, s ' write output to file Close #num End Sub
In this program, two variables called S and Num, are considered as string and integer. The open statement is used to create a text file with the name test. A column called “Hello World” is declared into the variable S.
When you run the VBA codeVBA CodeVBA code refers to a set of instructions written by the user in the Visual Basic Applications programming language on a Visual Basic Editor (VBE) to perform a specific task. manually or using the F5 key, the output is written into the immediate window, and the file at a time is shown in the folder.
The output to file is shown in the below-mentioned figure.
Printing output to file is beneficial when long text is presented.
Example #3 – Displaying the Factorial of a Number in the Immediate Window
This example illustrates the use of the debug—a print statement to show the factorial of a number.
Public Sub Fact() Dim Count As Integer Dim number As Integer Dim Fact As Integer number = 5 Fact = 1 For Count = 1 To number Fact = Fact * Count Next Count Debug.Print Fact End Sub
To determine the factorial, three variables are considered, including the count, number, and fact. For loop is taken to repeat the multiplication of fact-value with count to determine factorial of the number.
Here, debug. The print statement is used outside the “for” loop to display the value after completing the circle. The output is determined.
If we use debug. Print statement inside the “for” loop, the fact-value is displayed for every recurring time, as shown in the figure.
Public Sub Fact() Dim Count As Integer Dim number As Integer Dim Fact As Integer number = 5 Fact = 1 For Count = 1 To number Fact = Fact * Count Debug.Print Fact Next Count End Sub
Run the code by pressing the F5 key and see the output in the immediate window. In this situation, we should consider the last value as the factorial of the given number.
Example #4 – Printing the Full name of the Active Workbook
This example explains how to print the current workbook name into the prompt window.
The program is developed, as shown in the figure.
Sub Activework() Dim count As Long For count = 1 To Workbooks.count Debug.Print Workbooks(count).FullName Next count Debug.Print count End Sub
Here ‘count’ is the variable taken to count the number of active workbooks and to display the full name of the active workbook. The full name and number of active workbooks are displayed, as shown in the figure.
The path of the workbook in the drives is accurately displayed by using the VBA debugprint statement.
Things to Remember
- The main issue with the debug .print is no text wrapping option for long strings in the immediate window
- The immediate window should be brought to top see the output in the user interface
- It is impossible to wrap the long text displayed in the Immediate Window. In this situation, the result needs to be shown to a file stored in the drive.
