jless is a command-line JSON viewer. Use it as a
replacement for whatever combination of less, jq, cat and your
editor you currently use for viewing JSON files. It is written in Rust
and can be installed as a single standalone binary.
jless is under active development. I often stream development live on
Twitch.
- Clean syntax highlighted display of JSON data, omitting quotes around object keys, closing object and array delimiters, and trailing commas.
- Expand and collapse objects and arrays so you can see both the high- and low-level structure of the data.
- A wealth of vim-inspired movement commands for efficiently moving around and viewing data.
- Full regex-based search for finding exactly the data you're looking for.
jless currently supports macOS and Linux. Windows support is planned.
You can install jless using various package managers:
