jql is a command-line tool for querying and processing JSON data. It uses its own compact query language to select values and structures from JSON input while returning JSON as output.
The tool supports selection by keys, indices and ranges together with operators for flattening structures, processing array elements and inspecting keys. It can work with files or standard input and includes support for streamed newline-delimited JSON.
This is free and open source software.
Key Features
- Query JSON data from the command line.
- Select object keys.
- Select multiple keys in arbitrary order.
- Select array elements by index.
- Select array and object ranges.
- Build arrays from multiple subqueries.
- Filter structures with lens selectors.
- Flatten nested arrays and objects.
- Return object keys and array indices.
- Process array elements in parallel with pipe operators.
- Pretty-print JSON output.
- Optional compact inline output.
- Read queries from files.
- Read JSON from standard input.
- Process newline-delimited JSON streams.
- Validate JSON data and return an appropriate exit status.
