经常需要知道创建 Microsoft Excel 文档的应用程序的版本号。 Aspose.Cells for JavaScript 通过 C++ 提供了 Workbook.builtInDocumentProperties 属性来实现此目的。
以下示例代码演示了如何使用Workbook.builtInDocumentProperties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。

<h1>Print Excel Version Example</h1>
<input type="file" id="fileInput" accept=".xls,.xlsx" multiple />
<button id="runExample">Run Example</button>
<a id="downloadLink" style="display: none;">Download Result</a>
<div id="result"></div>

<script src="aspose.cells.js.min.js"></script>
<script type="text/javascript">
const { Workbook, SaveFormat, Worksheet, Cell, Utils } = AsposeCells;
AsposeCells.onReady({

"NotoSansSC-Regular.ttf"

}).then(() => {
console.log("Aspose.Cells initialized");
});
document.getElementById('runExample').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');
const resultDiv = document.getElementById('result');
if (!fileInput.files.length) {
resultDiv.innerHTML = '<p style="color: red;">Please select one or more Excel files.</p>';
return;
}
let outputHtml = '<h2>File Versions</h2><ul>';
for (const file of fileInput.files) {
const arrayBuffer = await file.arrayBuffer();
// Instantiating a Workbook object from the uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Access built-in document properties and read version
const version = workbook.builtInDocumentProperties.version;
console.log(file.name + " Version: " + version);
outputHtml += `<li><strong>${file.name}</strong>: ${version}</li>`;
}
outputHtml += '</ul>';
resultDiv.innerHTML = outputHtml;
});
