void Convert_Transitional_to_Strict(string input_filepath, string output_filepath)
{
    Excel.Application app = new Excel.Application(); // Create Excel instance
    app.DisplayAlerts = false; // Don't display any Excel prompts
    Excel.Workbook excelWorkbook = app.Workbooks.Open(input_filepath); // Create workbook instance and open Excel Workbook for conversion
    excelWorkbook.SaveAs(output_filepath, 61); // Save file as .xlsx Strict
    excelWorkbook.Close(); // Close the Workbook
    app.Quit(); // Quit Excel Application
