Often you need to know the version number of the application that created a Microsoft Excel document. Aspose.Cells for JavaScript via C++ provides the Workbook.builtInDocumentProperties property for this purpose.
The following sample code demonstrates the use of the Workbook.builtInDocumentProperties property. It loads Excel files created with Microsoft Excel 2003, 2007, 2010 and 2013 and prints the version number of the application that created these Excel documents.

<title>Aspose.Cells Example - Print Excel Version</title>
</head>
<body>
<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>
</body>
<script src="aspose.cells.js.min.js"></script>
<script type="text/javascript">
const { Workbook, SaveFormat, Worksheet, Cell, Utils } = AsposeCells;
AsposeCells.onReady({

}).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);
