可能的使用场景
您可以如下面截图所示，用 Microsoft Excel 保护或取消保护共享工作簿。Aspose.Cells for JavaScript 通过 C++ 也支持此功能，使用 Workbook.protectSharedWorkbook(string) 和 Workbook.unprotectSharedWorkbook(string) 方法。
密码保护或取消保护共享工作簿
以下示例代码创建一个工作簿并保护它，同时启用共享，然后将其另存为 输出 Excel 文件。截图显示当您尝试取消保护时，Microsoft Excel 会提示您输入密码以取消保护。
示例代码
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Protect Shared Workbook Example</h1>
<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<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 } = AsposeCells;
AsposeCells.onReady({

console.log("Aspose.Cells initialized");
});
document.getElementById('runExample').addEventListener('click', async () => {
// Creating an empty Workbook
const workbook = new Workbook();
// Protect the Shared Workbook with Password
workbook.protectSharedWorkbook("1234");
// Uncomment this line to Unprotect the Shared Workbook

// Saving the modified Excel file
const outputData = workbook.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
