IronXL enables C# developers to protect cells in their applications without the need for Excel to be installed. It offers all Excel functions with enhanced security measures.

We highly discourage the use of Excel interop in any web application or any application where the precise version of Excel is not installed. However, IronXL can provide all the functions that Excel offers without Excel interop. By using IronXL, you do not need to have Excel installed on any particular computer to use Excel in your C# application. Additionally, it can create, edit, import, generate, and export Excel documents without interop, becoming a popular C# Excel library.
IronXL allows you to use data from any source, including interop with another C++ application. If, for instance, you have interop with a proprietary C++ system, IronXL can extract data and create an Excel file without requiring Excel interop or Excel to be installed on your computer. This is essential for the .Net core, where Excel cannot be installed in an interop-compatible format for Mac and Linux targets or internet hosts.
IronXL can accomplish almost anything that Excel can achieve without interop in creating an Excel file. As for using interop with IronXL, we cannot think of any use cases where it might be necessary.
