EPPlus é uma biblioteca .NET Framework/.NET Core para gerenciar planilhas Office Open XML , distribuídas via Nuget . Veja nossa página de Projeto Básico de Software para frameworks .NET suportados. EPPlus é totalmente escrito em código gerenciado e não depende de nenhuma outra biblioteca, como o Microsoft Excel.

A biblioteca foi projetada pensando no desenvolvedor. Nosso objetivo sempre foi que um desenvolvedor com conhecimento de Excel ou qualquer outra biblioteca de planilhas se atualize facilmente com a API. Ou – como alguém disse – inteligência para a vitória!
