    Tools

    Small, sharp command-line tools and indexes: data conversion, CSV to SQL, gist search.

    The category holds 72 original repositories, written most often in JavaScript, Ruby, Elixir and Python. Featured: Gists search, json2csv and csv2psql.

    Key concept: Open source.

    How categories are made: nobody assigns them by hand. A repository falls into a category when its name, description or topics match the rule’s keywords, otherwise its primary language decides; forks and mirrors never count as the owner’s work.
