jnv

interactive JSON viewer and jq filter editor

TLDR

Open a JSON file for interactive filtering

$ jnv [path/to/data.json]

Filter JSON from stdin

$ cat [path/to/data.json] | jnv

Open with a default filter applied

$ jnv --default-filter '.[0]' [path/to/data.json]

Use a custom configuration file

$ jnv -c [path/to/config.toml] [path/to/data.json]

Write the filtered result to stdout on exit

$ jnv --write-to-stdout [path/to/data.json]

jnv is an interactive JSON viewer and jq filter editor. It provides a split-pane interface with a filter editor at the top and a syntax-highlighted JSON view below that updates in real time as you type your jq filter. Inspired by jid and jiq, jnv uses jaq internally to apply filters, eliminating the need to install jq separately.The tool supports JSON files and JSON Lines input, configurable UI through TOML configuration, hint message toggling, and adjustable reactivity including debounce times.

PARAMETERS

INPUT

Path to a JSON file. If omitted or "-", reads from stdin.

-c, --config file

Path to a TOML configuration file.

--default-filter filter

Default jq filter to apply to input data.

--write-to-stdout

Write the current JSON result to stdout when exiting.

-h, --help

Print help information.

-V, --version

Print version.

CAVEATS

Uses jaq (not jq) internally, so some advanced jq features or edge cases may behave differently. Large JSON files may impact responsiveness of the live preview. Supports JSON and JSON Lines input.

HISTORY

jnv was created by ynqa and is written in Rust. It was designed to provide a more polished and self-contained interactive JSON exploration experience compared to earlier tools like jid and jiq.
