rq (Record Query) is a Rust command-line tool for ad-hoc analysis and transformation of streams of structured records, similar to awk/sed but for record data instead of text. It reads and writes many formats including JSON, Avro, MessagePack, YAML, TOML, CSV, CBOR, and Protobuf, and ships as a dependency-free binary.

Use cases

• convert to yaml from the command line
• read avro files without hadoop
• transform messagepack data to
• inspect protobuf records in a stream
• convert csv to toml
• explore structured data files ad hoc
• pipe structured records between formats in shell scripts

When to choose

• you need a fast, dependency-free binary for converting between structured data formats
• you want awk/sed-style ad-hoc exploration of record data in the terminal
• you work with formats like Avro, MessagePack, or Protobuf that common tools don't handle

When to avoid

• you need built-in query/JavaScript evaluation, which was removed from the tool
• you need actively developed features or timely bug fixes
• you only need JSON processing, where jq is a more mature choice
