I have a file as below

Emp1|FirstName|MiddleName|LastName|Address|Pincode|PhoneNumber
1234|FirstName1|MiddleName2|LastName3| Add1 || ADD2|123|000000000
2345|FirstName2|MiddleName3|LastName4|
 Add1 || ADD2|
 234|000000000

OUTPUT :

Emp1|FirstName|MiddleName|LastName|Address|Pincode|PhoneNumber
1234|FirstName1|MiddleName2|LastName3| Add1 || ADD2|123|000000000
2345|FirstName2|MiddleName3|LastName4| Add1 || ADD2|234|000000000
