SQL SP Suggestion

Question

I have a SP that runs everynight to Insert and Update the content of a table based on an excel file (Excel 2010 on
Windows Server 20008 R2). Below is my SP and the image represents my table's structure and the excel file format. I just need to double check my SP with you guys to make sure I am doing this correctly and if I am on the right track. The excel file includes
3 columns both Cust_Num and Cust_Seq are primary since there would never be a case that same combination of Cust_Num and Cust_Seq exist for a customer name. For example, for Cust_Num = 1 and Cust_Num=0 there will never be another of same combination of Cust_Num
being 1 and Cust_Num being 0. However the name will usually repeat in the spreadsheet. So, would you guys please let me know if the SP is correct or not? (in the SP first the Insert statement runs and then the Update Statement):
First The Insert runs in the SP
INSERT INTO Database.dbo.Routing_CustAddress
SELECT a.[Cust Num],a.[Cust Seq],a.[Name]
FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0',
'Excel 8.0;HDR=YES;Database=C:\Data\custaddr.xls;',
'SELECT*
FROM [List_Frame_1$]') a Left join Routing_CustAddress b
on a.[Cust Num] = b.Cust_Num and a.[Cust Seq] = b.Cust_Seq where b.Cust_Num is null
***Then the Update Runs in the SP
UPDATE SPCustAddress
SET SPCustAddress.Name = CustAddress.Name
FROM ArPd_App.dbo.Routing_CustAddress SPCustAddress
INNER JOIN OPENROWSET('Microsoft.ACE.OLEDB.12.0',
'Excel 8.0;HDR=YES;Database=C:\Data\custaddr.xls;',
'SELECT *
FROM [List_Frame_1$]')CustAddress
ON SPCustAddress.Cust_Num = CustAddress.[Cust Num]
AND SPCustAddress.Cust_Seq = CustAddress.[Cust Seq]

Looks fine based on your explanation
You may use merge to do both operation in single step
