JSON Explorer CLI

CLI tool for progressive, layer-by-layer exploration of JSON files. Pass a file and an optional dot-separated path to inspect keys, types, and previews — one level at a time, no pager, no state.

Part of the admin-skills monorepo.

Quick Start

Requires Node.js >= 22.18 (TypeScript is run natively via Node's built-in type-stripping — no compiler or loader needed).

# run without installing
npx @askills/json-explorer-cli data.json

# or install globally
npm install -g @askills/json-explorer-cli
json-explorer data.json

Usage

Usage: json-explorer <file> [path]

Explore a JSON file layer by layer.

Arguments:
  file                  Path to the JSON file
  path                  Dot-separated path to a nested value (optional)

Examples:
  json-explorer data.json
  json-explorer data.json users
  json-explorer data.json users.0
  json-explorer data.json users.0.name

Each invocation lists the children of the targeted node: the full key path, a type label (string, number, array[N], object, …), and a short preview for scalar values. Drill deeper by appending the next key to the path.

Development

No build step needed for development — Node runs the TypeScript source directly.

pnpm install
pnpm test
pnpm start data.json
