EPPlus is a .NET library for creating, reading, and modifying Office Open XML Excel workbooks (xlsx/xlsm) entirely in managed code, with a formula calculation engine, charts, pivot tables, and no dependency on Microsoft Excel. It is dual-licensed under Polyform Noncommercial for noncommercial use and a paid commercial license, and is distributed via NuGet.
Use cases
- generate excel reports from .net
- read and write xlsx files in c#
- create spreadsheets without excel installed
- calculate excel formulas programmatically
- add charts and pivot tables to workbooks
- export data to excel in asp.net
- modify existing excel workbooks in .net
When to choose
- you need a mature, feature-rich Excel library for .NET with formula calculation, charts, and pivot tables
- you want managed code with no dependency on Microsoft Excel or COM interop
- you can comply with the Polyform Noncommercial license or purchase a commercial license
When to avoid
- you need a permissively licensed (MIT/Apache) library for commercial use without paying
- you work outside the .NET ecosystem
- you need to manipulate legacy .xls binary files rather than Open XML formats
