Solution 1

to read the file in step 2 you can use the below piece of code:

C#

OleDbConnection connection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<<absolute path of the excel file including the file name>>;Extended Properties=Excel 8.0");
OleDbDataAdapter da = new OleDbDataAdapter("select * from <<sheet name in the file>>", connection );
DataTable dt = new DataTable();
da.Fill(dt);

Now you have all the data in a datatable.
You can validate the data and make changes as you want.

For step 3 you can make a procedure for updating the status column on a where clause.
You can call the procedure for every row of the datatable from the code

solve the problem

string oledbConnectionString = string.Empty;
OleDbConnection conn = null;
oledbConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + filepath + "; Extended Properties=Excel 8.0;";
conn = new OleDbConnection(oledbConnectionString);
if (conn.State == ConnectionState.Closed)
{
conn.Open();
}
OleDbCommand command = new OleDbCommand("Select * from [sheet1$]", conn);
OleDbDataAdapter objAdapter = new OleDbDataAdapter();
objAdapter.SelectCommand = command;
DataSet objDataset = new DataSet();
objAdapter.Fill(objDataset, "Report");
conn.Close();
return objDataset.Tables[0];
