Generate AI-Powered JSON Instantly with This Free Chrome Extension

Question

Working with JSON can be frustrating, especially when you're prototyping APIs, creating mock data, or formatting payloads on the fly.

That’s why I built JSON AI Generator – Smart JSON from Plain Text — a free Chrome extension that turns simple English into valid JSON structures using AI.

Key Features:

✅ Generate JSON from plain text using AI (e.g., "a list of 3 users with name, email, and age")

✅ No login required

✅ Works entirely inside your browser — no data is sent to servers

✅ Built for developers, testers, and API enthusiasts

✅ Supports JSON preview, formatting, and validation

✅ Available as both a Chrome extension and a web version

Why It’s Useful:

• Speeds up mock API creation
• Helps non-tech teammates generate JSON easily
• Great for quick demos, testing, or teaching data structures
