2 min readApr 20, 2025

Ever struggled to understand a deeply nested JSON from an API response? What if you could just ask an AI what the data means?

Introducing JSON AI Inspector: a free and open-source web app built with Streamlit to format, analyze, compare, and generate JSON data using artificial intelligence.

✨ Key Features

1. JSON Formatting and Export

Syntax-highlighted JSON display
Export JSON to CSV (Excel-compatible)
Auto-generate type definitions for:
Python
Go
TypeScript

2. AI-Powered Analysis (Groq API)

Ask natural language questions about your JSON
Get intelligent and contextual answers
Ideal for debugging APIs and exploring structured data

3. JSON Comparison Tool

Drop in two JSON files and compare side-by-side
Visual diff of added, removed, or modified fields
Generate and export a comparison report

4. Mock Data Generation

Automatically generate realistic JSON mock data
Supports types like string, int, email, url, objectId, etc.
Type inference for arrays and nested objects
Export test-ready datasets

🧩 Additional Features

Multilingual support (English and Spanish)
Light and dark mode themes
Session history tracking
Stateless interaction with session memory

🚀 How to Get Started

Clone the repository:

git clone https://github.com/json-ai-tools/json-ai-inspector.git
cd json-ai-inspector

2. Install the dependencies:

pip install -r requirements.txt

3. (Optional) Add your Groq API key to enable AI features:

echo "GROQ_API_KEY=your-api-key" > .env

4. Launch the app:

streamlit run app.py

💡 Use Cases

Inspecting API responses quickly
Generating sample datasets for testing
Auto-generating type definitions from real data
Detecting inconsistencies or empty fields in JSON

👩‍💻 Who is this tool for?

Backend engineers
QA engineers and testers
API developers
Educators and learners working with data

🤯 It’s More Than Just a Pretty Formatter

Instead of scrolling endlessly through JSON, just ask:

“What fields are required?”
“Which values are empty?”
“Are there inconsistencies in structure?”

And the AI will tell you — clearly and intelligently.
