In addition to jq (already mentioned) here are some other useful CLI tools for dealing with JSON data. Descriptions are directly from GitHub. Note: dsq also has a companion GUI app called DataStation[0] if you're looking for that. fx: Command-line JSON processing tool - https://github.com/antonmedv/fx dasel: JSON, YAML, TOML, XML, and CSV query and modification tool - https://github.com/TomWright/dasel dsq: CLI tool for running SQL queries against JSON, CSV, Excel, Parquet, and more - https://github.com/multiprocessio/dsq gron: Make JSON greppable - https://github.com/tomnomnom/gron jello: Filter JSON and JSON Lines data with Python syntax - https://github.com/kellyjonbrazil/jello jless: Command-line pager for JSON data - https://github.com/PaulJuliusMartinez/jless jid: Json incremental digger - https://github.com/simeji/jid jql: JSON que

If you like python you might check out jello[0]. I basically wrote it to give you the power and simplicity of python without the boiler plate in a jq-like form-factor. Jello also allows you to use dot-notation instead of dict bracket notation, so it does make things easier on the command line. Also, there is jellex[1], which is a TUI wrapper around jello that can help you build your queries. [0] https://github.com/kellyjonbrazil/jello [1] https://github.com/kellyjonbrazil/jellex
In Tips on adding JSON output to your CLI app
Well, there is XPath 3.1 if you want standards[1] but my point was simply that it depends on whether your question is “I need compatibility with existing jq scripts”, “I need an embeddable library I can integrate in other programs”, or “I want to process JSON for my own usage”. For example, someone who works with a lot of Python might prefer something like https://github.com/kellyjonbrazil/jello to write comprehensions using the full capabilities of Python, especially since that would provide a direct path to using the final expressions in a Python program or even embedded in one of the environments where Python is used as a scripting language. Is that a viable alternative? The answer depends entirely on who's asking. 1. https://www.w3.org/TR/xpath-31/#id-introduction
