Update existing data with excel import I have user table in my DB. I have 1 excel sheet having list of some users (not all) with changes. How can I Update the values given in excel sheet to my user table? is it possible with import data option?
I only learned this in the past year.  You can query an excel sheet as if it's a table.  As long as your keys are also in excel you can join the excel sheet to the user table.

You can have a look at this Microsoft Article that discusses options for importing from Excel to SQL Server.
