fq

jq for binary formats — a tool, language, and set of decoders for querying and transforming binary and text data.

Desktopfreeglobal

A desktop tool, language, and set of decoders for decoding, querying, slicing, and transforming binary and text data using a jq-like query language and an interactive REPL with autocompletion. It provides structured views of nested formats to avoid one-off parsing scripts and raw hexdump byte‑math, aimed at reverse engineers, forensic analysts, and developers debugging binary protocols and file formats; not intended for data already in structured text formats.
