CompuMaster.Excel.MsExcelComInterop

Use Microsoft.Office.Interop.Excel v15 (MS Office 2013) or higher, for solutions targetting .NET Framework 4.8 or .NET 6 or higher

Allow COM interop at clients without using Microsoft.Office.Excel.Interop assemblies for light-weight deployments of applications to customers/clients, regardless of the installed version of Microsoft Office

Limitation: supports only a very tiny, but often-used feature set, e.g. print, export to PDF, run VBA code

Diagnostic logs

Use ExcelApplication.DiagnosticLogFiles to inspect the files associated with the wrapper's Excel process. The wrapper removes confirmed logs after a successful quit and trims trailing NUL padding after an abnormal exit. Set PreserveDiagnosticLogFiles to true to retain the files byte for byte.

Licensing

  • Please see license file in project directory
  • Pay attention to required licensing of the 3rd party components (commercial vs. community licensing, user licensing, etc.)

Examples

Quick-Start: Create a workbook and put some values and formulas, then output the result to console

CompuMaster.Excel.MsExcelComInterop.ExcelApplication? excelApp = null;
CompuMaster.Excel.MsExcelComInterop.ExcelWorkbook? wb = null;
try
{
    // Open excel engine
    try
    {
        excelApp = new CompuMaster.Excel.MsExcelComInterop.ExcelApplication();
    }
    catch
    {
        System.Console.WriteLine("Platform not supported or MS Excel application not installed");
        return;
    }

    // Workbook actions
    string sourceTestFile = "test.xlsx";
    string targetTestFile = "test.pdf";
    if (System.IO.File.Exists(targetTestFile))
        System.IO.File.Delete(targetTestFile);
    wb = excelApp!.Workbooks.Open(sourceTestFile);
    wb.ExportAsFixedFormat(CompuMaster.Excel.MsExcelComInterop.Enumerations.XlFixedFormatType.xlTypePDF, targetTestFile);
}
finally
{
    // Close and dispose everything
    if (wb != null && wb.IsClosed == false)
        wb.Close();
    if (excelApp != null)
        excelApp.Dispose();
    CompuMaster.ComInterop.ComTools.GarbageCollectAndWaitForPendingFinalizers();
}
