App::fsql - https://metacpan.org/release/App-fsql

Perl5, using SQL::Statement, a pure Perl SQL parsing and execution engine

Perform SQL queries against files in CSV/TSV/LTSV/JSON/YAML formats. Each file will be regarded as a SQL table. Data grouping, joining, or filtering with SQL expressions and functions.
As a bonus, you can also modify data (currently CSV only) via SQL INSERT or DELETE commands.

Added in d0db7bc. The custom SQL interpreter is really interesting. Thank you for the suggestion!
