推荐答案

从Excel C开始将是非常困难的API并编写一个有用的API，尤其是对于需要可伸缩性和效率的Web应用程序，以及其他所有API。这是一篇关于CodeProject的文章，讨论了这个问题，通过C ++访问Excel电子表格 [ ^ ]。



因此，我建议使用可以从网站调用的具有C ++库的第三方库。其次，为什么使用C ++，您使用什么运行时进行Web开发？

C ++ Excel库读取/写入xls / xlsx文件 - LibXL [ ^ ]



您会注意到我只分享了那些文章和库谈论读/写Excel文件，而不是比较它们。因为这是业务逻辑，你必须写，因为你没有提到任何相关的东西，我无法帮助你。



最后，接受我的建议，找到一个有用的Web应用程序开发框架，使用ASP.NET Core或Node.js，并为这些运行时找到一个有用的库。与任何用于网络编程的C ++运行时不同，它将是您的和平开发。是的，可以开发Node.js以利用C ++库和帮助程序，与ASP.NET Core一样，您始终可以在那里导入C ++库。最好的部分是你可以获得这些运行时的本机库。

It would be very difficult to start with the Excel C API and write a useful API, especially for a web application where scalability, and efficiency are required, on top of everything else. Here is such an article on CodeProject that talks about this, Accessing Excel Spreadsheets via C++[^].

Thus, I would recommend using a third-party library that has C++ library that you can call from a website. Secondly, why C++, what runtime are you using for web development?

XLW - A C++ wrapper for the Excel C API download | SourceForge.net[^]
C++ Excel Library to read/write xls/xlsx files - LibXL[^]

You will notice that I have only shared the articles and libraries that talk about reading/writing Excel files, not comparing them. Because that is the business logic, that you have to write, and since you did not mention anything about that, I cannot help you with it.

Lastly, take my advice, find a useful web application development framework, go with ASP.NET Core, or Node.js, and find a useful library for those runtimes. It will be a peaceful development of yours, unlike with any C++ runtime for network programming. And yes, Node.js can be developed to utilize C++ libraries and helpers, same is with ASP.NET Core, you can always import C++ libraries there. Best part is that you can get the native libraries for these runtimes.
