jsongrep is a command-line tool and Rust library for querying structured data with a JSONPath-inspired language based on regular path expressions.
It can read from files or standard input, focuses on matching paths through nested data, and is designed for fast querying of serialized documents rather than transformation pipelines.
This is free and open source software.
Key Features
- Supports JSON, JSONL/NDJSON, YAML, TOML, CBOR, and MessagePack documents.
- Auto-detects input format from file extension and also accepts an explicit format flag.
- Can print matched path locations, suppress path headers, or force them when output is piped to other tools.
- Includes fixed-string field search at any depth, case-insensitive search, and match counting options.
- Generates shell completions and man pages from the command line.
