you can use below mentioned code data excel columns in datatable. 

system.data.oledb.oledbconnection myconnection ; system.data.dataset dtset ; system.data.oledb.oledbdataadapter mycommand ; myconnection = new system.data.oledb.oledbconnection("provider=microsoft.jet.oledb.4.0;data source='c:\\csharp.net-informations.xls';extended properties=excel 8.0;"); mycommand = new system.data.oledb.oledbdataadapter("select * [sheet1$]", myconnection); mycommand.tablemappings.add("table", "testtable"); dtset = new system.data.dataset(); mycommand.fill(dtset); datagridview1.datasource = dtset.tables[0]; myconnection.close();

note:- need change excel workbook path column names according excel spreadsheet
