This is a bit of work, which is why everyone is bidding $100 or so. I have designed very many systems for doing this already, and the low bid is because it will take me no time to whip up a version that works for you. To show that I am not blowing smoke, you can try to download one mainstream system I already made which specifically deals with getting data between formats and stores it to SQLite DBs in a stand-alone windows version from here:

That's a private host so your browser should warn you about downloading things from the net etc, as it should. It is safe, b ut scan it to be sure. Once installed you can make a new DB (just set a filename), then find the "Import from File" button next to the Query box (top middle) and select your CSV. In the starting screen, even before it hits the DB format, you can already manipulate, replace, add columns etc. Once imported you can sort, add, delete etc. etc. That one you can have for free, but I will make a version that does what you need specifically or easier, and that's what the bid is for :)
You can mail me direct (use the bug-report mailer form that system) if you have any questions.
Have a great day!
