Tool for importing excel spreadsheets

What's the best tool to import an excel spreadsheet in C# these days? I'm currently using Interop.Excel.dll.

From stackoverflow

• You can use the Jet OLEDB Provider:

  connection.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
             "Data Source=c:\somepath\mySpreadsheet.xls;" & _
             "Extended Properties=""Excel 8.0;HDR=Yes"""
  

  Where "HDR=Yes" means that there is a header row in the cell range (or named range), so the provider will not include the first row of the selection into the recordset.

  ProfK : I have just found a funny using Jet: My column headings are dates, and these get transformed into arbitrary column names like 'F1', 'F2', etc. I'll comment again if I find a solution.
