When it comes to handling CSV, the usual hint is to use Text::CSV (and Text::CSV_XS). For the data shown, readline and substr should be sufficient. When the data becomes slightly more complex, Text::CSV is the way to go, because it can handle the crazy edge cases you never even thought of.

Having said that, there is also DBD::CSV, sitting on top of Text::CSV_XS and providing access to CSV files as if they were any other ordinary SQL database. And at that point, you no longer have to think about the CSV files at all. Just SELECT from the CSV files using one database handle connected to the CSV files "database", and INSERT/UPDATE to SQLite (or any other database) using a second database handle connected to SQLite (or any other database).
