Hello Narasiman,

The error "'microsoft.ace.oledb.12.0' provider is not registered on the local machine" is pretty much self-explanatory. isn't it. Try downloading the provide from (http://www.microsoft.com/en-us/download/details.aspx?id=13255) and installing it.

The message tells you exactly what the problem is; you have not loaded the ACE driver onto the machine where you are trying to read the Excel file.

C#

String ProviderExcel = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=";
String ExtendedPropertiesExcel = "Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\"";
String connString = ProviderExcel + filePath + ";" + ExtendedPropertiesExcel;
System.Data.OleDb.OleDbConnection cn = new System.Data.OleDb.OleDbConnection(connString);
  try
  {
    cn.Open();
    DataTable schemaTable = cn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });
    string SheetName = schemaTable.Rows[0][2].ToString();
    StringBuilder SelectStatement = new StringBuilder();
    SelectStatement.Append("SELECT * FROM [").Append(SheetName).Append("]");
    System.Data.OleDb.OleDbDataAdapter da = new System.Data.OleDb.OleDbDataAdapter(SelectStatement.ToString(), cn);


    DataTable objDataTable = new DataTable();
    da.Fill(objDataTable);
  }

Try This code. Definatly it will work..
