hi ragahavendra,
You can use bapi to create entries into the table.
goto se37 -> type BAPIADDR* and press f4 , you will find many bapi to work with,
you can use BAPIADDREMPIT_SIMULATECREATION bapi.
after getting values from the excel file.. you would have values in the internal table . loop the internal table, inside the loop call this bapi, this will create entry in the table.
For address number , you can call number range ADRNR.
