fx is a terminal-based JSON viewer and processor written in Go. It provides an interactive TUI for exploring JSON and a powerful CLI for transforming JSON with JavaScript expressions.

Use cases

Explore large JSON files interactively in the terminal
Transform JSON streams using JavaScript expressions
Extract specific fields from JSON via command-line pipelines
Preview and edit JSON, YAML, or TOML data quickly
Process line‑delimited JSON logs in real time
Integrate JSON manipulation into CI/CD scripts

When to choose

You need a fast, single‑binary tool for JSON inspection and transformation
You prefer using JavaScript syntax for data manipulation without writing a full script
You work primarily in terminal environments on Linux, macOS, or Windows
You want built‑in autocompletion and a TUI for navigating complex JSON structures

When to avoid

You require a full‑featured IDE or GUI for JSON editing
You need support for binary formats other than JSON/YAML/TOML
You prefer a library to embed JSON processing directly in your application
