This post shows how to import and export .xls or .xlsx (Excel files) in ASP.NET Core. And when thinking about dealing with excel with .NET, we always look for third-party libraries or component. And one of the most popular .net library that reads and writes Excel 2007/2010 files using the Open Office Xml format (xlsx) is EPPlus. However, at the time of writing this post, this library is not updated to support .NET Core. But there exists an unofficial version of this library EPPlus.Core which can do the job of import and export xlsx in ASP.NET Core. This works on Windows, Linux and Mac.
