NativeExcel does not require installed Microsoft Office, it writes and reads excel files directly.
NativeExcel can be used as a replacement of standard Excel components, it has the same object model, properties and methods.
With NativeExcel v3.x you can open and modify an existing spreadsheet.

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.)

We are going to add support for all these features in the near future.
