I don't know what type of data you have.But for an excel data like shown in this link http://www.freeimagehosting.net/image.php?f8d4ef4173.png, you can use the following code to load into data table.

    private void Form1_Load(object sender, EventArgs e)
    {   
       try
       {        
            DataTable sheetTable = loadSingleSheet(@"C:\excelFile.xls", "Sheet1$");
            dataGridView1.DataSource = sheetTable;
       }
       catch (Exception Ex)
       {
            MessageBox.Show(Ex.Message, "");
       }  
    }        

    private OleDbConnection returnConnection(string fileName)
    {
        return new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + "; Jet OLEDB:Engine Type=5;Extended Properties=\"Excel 8.0;\"");
    }

    private DataTable loadSingleSheet(string fileName, string sheetName)
    {           
        DataTable sheetData = new DataTable();
        using (OleDbConnection conn = this.returnConnection(fileName))
        {
           conn.Open();
           // retrieve the data using data adapter
           OleDbDataAdapter sheetAdapter = new OleDbDataAdapter("select * from [" + sheetName + "]", conn);
            sheetAdapter.Fill(sheetData);
        }                        
        return sheetData;
    }
