EPPlus

EPPlus è una libreria .NET Framework/.NET Core per la gestione di fogli di calcolo Office Open XML, distribuita tramite Nuget. La versione 5 supporta .NET Framework dalla versione 3.5 e .NET Core dalla versione 2.0. EPPlus non ha dipendenze da nessun'altra libreria come Microsoft Excel.

La libreria è stata progettata tenendo presente lo sviluppatore.
