jss, a jq-like CL tool for manipulating JSON files using CSS selectors

In plain words

jss is a command-line tool for processing and manipulating JSON files using CSS-like selectors instead of traditional query syntax. It applies JSONSelect syntax to let users find and extract specific data from JSON documents in a familiar way. The tool is designed for developers and system administrators who work with JSON data from the command line and prefer CSS selector patterns over other query languages.

  JSON QueryOct 2025 · jsonquerylang.org · ▲154

  I'm working on a tool that will probably involve querying JSON documents and I'm asking myself how to expose that functionality to my users. I like the power of `jq` and the fact that LLMs are proficient at it, but I find it right out impossible to come up with the right `jq` incantations myself. Has anyone here been in a similar situation? Which tool / language did you end up exposing to your users?
