What is the procedures to im****t data from excel

Hello,

Trying to im****t data from excel that originally ex****ted from other 
database is alwasy a problem. In this case when we want to APPEND the data
 
into our current database

What is the best way/ steps to follow. When I made a trial and error, it 
seems the following we should be ( pls correct me when I am wrong):

1. Try to im****t data for tables which become a mother records ( primary
key)
2. Then im****t the data for table that has child records ( foreign key)
3. Delete the primary key in the child table, let computer adds it when
you 
process im****t.

Thanks for any idea provided.
