At some point, programmers may need to determine if an Excel file contains VBA macros. This article is going to show you how to programmatically determine if an Excel file contains VBA macros in C# and VB.NET using Spire.XLS.
Detail steps:
Step 1: Instantiate a Workbook object and load the Excel file.
Workbook workbook = new Workbook();
workbook.LoadFromFile("Macro.xlsm");
Step 2: Determine if the Excel file contains VBA macros.
bool hasMacros = false;
hasMacros = workbook.HasMacros;
if (hasMacros)
{
Console.WriteLine("The file contains VBA macros");
}
else
{
Console.WriteLine("The file doesn't contain VBA macros");
}
Screenshot:
Full code:
[C#]
using System;
using Spire.Xls;
namespace Determine_if_Excel_file_contains_macros
{
class Program
{
static void Main(string[] args)
{
//Instantiate a Workbook object
Workbook workbook = new Workbook();
//Load the Excel file
workbook.LoadFromFile("Macro.xlsm");
bool hasMacros = false;
//Determine if the Excel file contains VBA macros
hasMacros = workbook.HasMacros;
if (hasMacros)
{
Console.WriteLine("The file contains VBA macros");
}
else
{
Console.WriteLine("The file doesn't contain VBA macros");
}
Console.ReadKey();
}
}
}
[VB.NET]
Imports System
Imports Spire.Xls
Namespace Determine_if_Excel_file_contains_macros
Class Program
Private Shared Sub Main(ByVal args As String())
Dim workbook As Workbook = New Workbook()
workbook.LoadFromFile("Macro.xlsm")
Dim hasMacros As Boolean = False
hasMacros = workbook.HasMacros
If hasMacros Then
Console.WriteLine("The file contains VBA macros")
Else
Console.WriteLine("The file doesn't contain VBA macros")
End If
Console.ReadKey()
End Sub
End Class
End Namespace
