可能的使用场景
以前，你需要更改整个线程的文化信息以处理特定文化格式的数字和日期，但现在Aspose.Cells for JavaScript通过C++提供了LoadOptions.CultureInfo属性，可以在不更改整个线程文化信息的情况下加载具有特定文化信息的工作簿。
使用特定系统的区域设置信息加载工作簿
下列示例代码演示如何使用特定系统文化信息加载工作簿以处理日期。

let uint8Arr;
if (fileInput.files.length) {
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
uint8Arr = new Uint8Array(arrayBuffer);
} else {
const encoder = new TextEncoder();
uint8Arr = encoder.encode(defaultHtmlContent);
}
// Instantiate Workbook from the HTML bytes (Aspose.Cells can load HTML content)
const workbook = new Workbook(uint8Arr);
// Save the workbook to XLSX format and provide a download link
const outputData = workbook.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'output.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Workbook created from HTML content. Click the download link to get the generated Excel file.</p>';
