JSON Formatting, Minification, and Syntax Auto-Repair

Working with raw API responses, logging dumps, and system configs often yields unreadable minified strings or slightly malformed JSON syntax (such as Python single quotes, unquoted keys, or trailing commas).

JSON Studio provides an intelligent Monaco-based editor with instant syntax diagnosis, one-click beautification, and automated repair.

1. Core Capabilities

• Beautify (2 or 4 Spaces): Expands nested objects and arrays with clear indentation and color-coded primitives.
• Minify / Compact: Strips all whitespace, tabs, and newlines to produce the lowest byte footprint for HTTP request bodies.
• Auto-Fix Broken JSON: Heals common mistakes:
  • Replaces single quotes with valid RFC double quotes.
  • Strips trailing commas in objects and arrays.
  • Quotes bare keys in JavaScript object literals.
  • Converts NaN, undefined, or Infinity to null or standard literals.

2. Step-by-Step Formatting Guide

Step 1: Input JSON Payload

Paste your payload into the left editor pane, or drag a .json file directly into the workspace.

Step 2: Select Operation

• Click Format (2 Spaces) or Format (4 Spaces) to beautify.
• Click Auto-Fix if the syntax validator flags red error gutters.
• Click Minify if you are preparing data for a compact REST payload.

Step 3: Copy or Export

Copy the sanitized JSON with a single click, or export it as a clean .json file.

// Example: Before Auto-Fix (Invalid JSON)
{
  name: 'Antigravity Studio',
  items: [1, 2, 3,],
}

// After Auto-Fix (Valid RFC 8259 JSON)
{
  "name": "Antigravity Studio",
  "items": [1, 2, 3]
}
