Import data from Excel to SQL Server by id

Question

I would be grateful if you can tell me how import data from Excel into a specific column based specific id - my amount of data is huge.

Table in Excel:

id	description
1	description for id 1
2	description for id 2
3	description for id 3
4	description for id 4

My table in SQL Server

id	name	description
1	one	null
2	two	null
3	three	null
4	four	null

I want a query something like this:

if (id in excel == id in SQL Server)
    SQL.description = excel.description

In my view, At first you can import all row from excel file into a table -eg excelTable-and finally update mainTable from join table with new table.

1)In SSMS right on your database/Tasks/Import Data 2)Select from excel file 3)update main table update mainTable set mainTable.description = excelTable.description from maintable inner join execlTable on mainTable.id = execlTable.id
