I'm a newbie interested in learning and implementing things I learn. I've been working on SQL Server 2014 these days and I'm loving it.
I've come across some scenario's where I would have an Excel document with 70,000 rows and about 10-12 columns imported into SQL Server (a table), make use of it to compare/insert/modify existing data in other tables. I'm currently using the manual feature available in GUI (right click >> Tasks >> Import) to import and export when needed; however, I've got informed by one of my colleagues that the same procedure can also be done through script/queries.
Can someone let me know what is the correct way of writing a query to import XLS, XLSX, CSV format files into a table?
P.S.: I've also tried reading some posts about OPENDATASOURCE
and OPENROWSET
where I've not been successful, always getting some errors about which I have no clue. So, looking to see if there are any other ways, and keen to learn their procedure.

I've used Openrowset a number of times for this task.
This code will create a table in SQL.
Ideally you want to create the table first and then use INSERT INTO instead of the SELECT INTO. That way you can control the column data types.
