}Paste raw, minified, or broken JSON and get back perfectly formatted output with syntax highlighting and clear error messages. Works with any valid JSON — objects, arrays, nested structures, Unicode.
Why Use a JSON Formatter?
Raw API responses, database exports, and config files often arrive as a single, unreadable line of JSON. A formatter turns this into structured, indented output you can read, debug, and copy at a glance.
Features of This Formatter
- Instant formatting — results appear as you type
- Syntax highlighting — keys, values, and types are colour-coded
- Error detection — invalid JSON is flagged with the exact line and character
- Collapsible nodes — fold nested objects to navigate large payloads
- Minify — toggle between pretty-print and minified output for copying to code
Common JSON Issues This Tool Catches
- Trailing commas (invalid in JSON, valid in JavaScript)
- Unquoted keys
- Single quotes instead of double quotes
- Unclosed brackets or braces
- Unexpected characters outside string literals
JSON in Automation Workflows
JSON is the universal data format for APIs, webhooks, and automation platforms. If you're building Make, Zapier, or n8n workflows and struggling with malformed JSON from a webhook, this formatter will help you diagnose the problem instantly. It's the tool I reach for constantly when mapping nested webhook payloads — see Make.com Webhook Tutorial and Make.com GoHighLevel Integration for real examples of the payload structures this untangles. For strict syntax validation rather than formatting, the JSON Validator is the companion tool.
