EPPlus is a .NET Framework/.NET Core library for managing Office Open XML spreadsheets, distributed via Nuget . Version 5 supports .NET Framework starting with version 3.5 and .NET Core starting with version 2.0. It is currently a single DLL and has no dependency on any other library such as Microsoft Excel. The library was designed with programmers in mind. Our goal has always been to make it easy for a developer with knowledge of Excel or another spreadsheet library to speed up the API. Or – as someone said – intelligent your way to victory!
