You can import your excel data to a DataSet and then play around with dataset and create your desired table. For eg when iterating through the first column you can check the string if it has 2 spaces before then add it to subcategory column and others to the category column. All you have to do is iterate through the rows of the DataSet and store your required values in a new datatable.

public DataSet ExcelToDS(string Path, string sheetname)
        {
            string xlsConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Path + ";Extended Properties=Excel 8.0;";
            string xlsxConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Path + ";Extended Properties=Excel 12.0";
            using (OleDbConnection conn = new OleDbConnection(xlsxConn))
            {
                conn.Open();
                string strExcel = "select * from [" + sheetname + "$]";
                OleDbDataAdapter oledbda = new OleDbDataAdapter(strExcel, xlsxConn);
                DataSet ds = new DataSet();
                oledbda.Fill(ds, sheetname);
                conn.Close();
                return ds;
            }
        }
