通常，你需要知道创建Microsoft Excel文档的应用程序的版本号。Aspose.Cells for Node.js via C++提供了一个Workbook.getBuiltInDocumentProperties()属性用于此目的。
以下示例代码演示了如何使用Workbook.getBuiltInDocumentProperties()属性。它加载由Microsoft Excel 2003、2007、2010和2013创建的Excel文件，并输出创建这些Excel文件的应用程序的版本号。
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
// Print the version number of Excel 2003 XLS file
let workbook = new AsposeCells.Workbook(path.join(dataDir, "Excel2003.xls"));
console.log("Excel 2003 XLS Version: " + workbook.getBuiltInDocumentProperties().getVersion());
// Print the version number of Excel 2007 XLS file
workbook = new AsposeCells.Workbook(path.join(dataDir, "Excel2007.xls"));
console.log("Excel 2007 XLS Version: " + workbook.getBuiltInDocumentProperties().getVersion());
// Print the version number of Excel 2010 XLS file
workbook = new AsposeCells.Workbook(path.join(dataDir, "Excel2010.xls"));
console.log("Excel 2010 XLS Version: " + workbook.getBuiltInDocumentProperties().getVersion());
// Print the version number of Excel 2013 XLS file
workbook = new AsposeCells.Workbook(path.join(dataDir, "Excel2013.xls"));
console.log("Excel 2013 XLS Version: " + workbook.getBuiltInDocumentProperties().getVersion());
// Print the version number of Excel 2007 XLSX file
workbook = new AsposeCells.Workbook(path.join(dataDir, "Excel2007.xlsx"));
console.log("Excel 2007 XLSX Version: " + workbook.getBuiltInDocumentProperties().getVersion());
// Print the version number of Excel 2010 XLSX file
workbook = new AsposeCells.Workbook(path.join(dataDir, "Excel2010.xlsx"));
console.log("Excel 2010 XLSX Version: " + workbook.getBuiltInDocumentProperties().getVersion());
// Print the version number of Excel 2013 XLSX file
workbook = new AsposeCells.Workbook(path.join(dataDir, "Excel2013.xlsx"));
console.log("Excel 2013 XLSX Version: " + workbook.getBuiltInDocumentProperties().getVersion());
