Jun 8, 2011 at 12:40 comment added Druid I tried using this in a project that builds pretty large Excel sheets. Excellent library, but extremely poor in performance. I just did a comparison for the project I'm working on: ClosedXML (v 0.53.3) took 92,489 ms whereas EPPlus (v 2.9.03, for testing - we can't use because it's GPL) took 16,500 ms.
