EPPlus is a .NET library for managing Office Open XML spreadsheets. The library is designed with the developer in mind allowing any developer with knowledge of Microsoft Excel or any other spreadsheet library to easily get up to speed with the API. EPPlus provides an intuitive programming interface to most of Microsoft Excel’s functionality, such as styling, charts, pictures/shapes, VBA/Form controls, formula calculation, tables, pivot tables, conditional formatting, data validation, etc. EPPlus' feature set and programming interface has always been driven by real world requirements and feedback from its very large user base (EPPlus has been downloaded by .NET Developers more than 40 million times).

EPPlus has been widely used in various .NET environments to create/read/update spreadsheets – in SAAS platforms and internal systems, on-premise and in the cloud. It has also made its way into the Docker/Web assembly world.
