Auto-Correct JSON — Fix Broken JSON Instantly

Auto-Correct JSON is a powerful feature in SimplyJSON that automatically fixes common formatting issues in your JSON data — so you don’t have to.

Whether you’re pasting from logs, copying API responses, or debugging a malformed snippet, Auto-Correct helps you format invalid JSON into valid, readable structure instantly.

✅ What It Fixes

• Quoting unquoted keys: name: "John" → "name": "John"
• Quoting unquoted string values: role: admin → "role": "admin"
• Removing trailing commas: { "name": "John", } → { "name": "John" }
• Replacing single quotes: 'name': 'John' → "name": "John"
• Adding missing braces: name: "John" → { "name": "John" }

🎯 Why It's Useful

Malformed JSON is common in:

• Logging systems
• Config files
• Developer handoffs
• Debugging tools

Manually fixing quotes and commas is time-consuming and error-prone. Auto-Correct does this in one click, saving time and frustration.

🧪 How It Works

You’ll find a checkbox labeled “Auto‑Correct JSON” below the buttons panel in both:

• JSON Formatter
• JSON Converter

Just paste your input, make sure the box is checked, and click Format or Convert. Invalid JSON gets cleaned and parsed behind the scenes.

🔒 Secure & Client-Side

Auto-correction and parsing happen entirely in your browser. Your data never leaves your device — ensuring privacy and performance.

💡 Pro Tip

Auto-Correct is great for rapid development and prototyping, but we always recommend validating the final JSON using our JSON Validator for production.
