Forks
EPPlus is a pretty solid tool and you probably don’t need any of the additional fluff they’re adding in the now paid version. Use these to circumvent the official EPPlus misleading “Deprecated” notice.

Most stars but no activity in the last 5 years
visualon/epplus
:
Actively maintained up till .NET 8 support but deprecated since May 28, 2025
One thing that I did stumble upon with the classic EPPlus is that it has a dependency on System.Drawing.Common
which only works on Windows. The non-free version has removed this dependency.
