There are a variety of methods to get data from Excel into SQL Server, and without knowing more details I'd suggest you look at SSIS in the first instance - [see this walkthrough][1]. I also suggest that once your data is in SQL Server (you could, for example, use a staging table to hold the data to be updated) you look at using the [MERGE statement][2] to update or insert the records as your criteria dictate.

dear Dave thank you very much for quick response My dear i will use merge method i will need to make 2 same tables 1st one to hold same values from excel and second one to store data after merge like table A and B A will hold all data uploaded by excel daily basis - Source table for merge B will hold all unique data new and old (updated and inserted )- target table for merge am i understanding right?

That sounds about right - import the data as is, then use MERGE to update the existing or insert the new records.
