NativeExcel2 for .NET

NativeExcel2 for .NET is a high-performance solution that allows to create, read and modify Excel spreadsheets on the fly from any .NET application.
A key feature of this version of NativeExcel for .NET is support for XLSX file format (Excel 2007/2010 file format).
NativeExcel2 does not require installed Microsoft Excel on the user’s computer, it writes and reads excel files directly.
NativeExcel2 is a single DLL written completely in managed C#.

Important notice

The current implementation for XLSX file format has some temporary limitations
The following features are not supported:
  • Any kind of graphic objects (images, notes, graphs, buttons etc.)
  • External references in formulas (references to external workbooks)
  • Data validation
  • Autofilters
We are going to add support for all these features in the near future.
