One approach to working with Excel files is to use the OpenXML SDK. This requires working with Office 2007 or higher. The beauty of it is that instead of going through the Interop, you work directly against the xml file for the Excel document, which makes it a good option for server usage. The downside is that the way the files are organized is fairly different from the way it is presented through Interop, so figuring out what is what can be a challenge. I haven't used it specifically for formatting, but I worked with it for creating or editing documents via C#, and it's blazing fast.

处理 Excel 文件的一种方法是使用 OpenXML SDK 。这需要使用 Office 2007 或更高版本。它的优点在于，您无需通过 Interop，而是直接针对 Excel 文档的 xml 文件进行工作，这使其成为服务器使用的一个不错的选择。缺点是文件的组织方式与通过 Interop 呈现的方式有很大不同，因此弄清楚文件是什么可能是一个挑战。我没有专门使用它进行格式化，但我使用它通过 C# 创建或编辑文档，而且速度非常快。

如果您需要使用 xls（97 到 2003），您可能需要尝试
