JSON Tools
Format, validate, minify, compare, and query JSON data with our comprehensive JSON toolkit. Perfect for developers, data analysts, and anyone working with JSON.
What are JSON Tools?
JSON (JavaScript Object Notation) is the standard data format for modern web applications. Our JSON Tools provide everything you need to work with JSON data: format it for readability, minify it for production, validate syntax, compare differences, and query with JSONPath.
Format & Beautify
Make JSON readable with proper indentation
Compare & Diff
Find differences between JSON objects
JSONPath Query
Extract data with path expressions
Format
Beautify with custom indentation
Minify
Remove whitespace for production
Validate
Check syntax correctness
Escape
Escape special characters
Unescape
Remove escape characters
Compare
Diff two JSON objects
JSONPath
Query JSON with paths
Select Action

How to Use JSON Tools
Choose Action
Select the operation you want: Format, Minify, Validate, Compare, or JSONPath Query.
Paste JSON
Enter or paste your JSON data in the input area. Use "Load Example" to see how it works.
Process
Click the action button to process your JSON. Errors will be shown if the JSON is invalid.
Copy Result
Copy the processed JSON to your clipboard and use it in your projects.
Common Use Cases
- ✓API Development: Format JSON responses from APIs for debugging and documentation purposes.
- ✓Configuration Files: Minify JSON config files to reduce file size for production deployment.
- ✓Data Comparison: Compare API responses or configuration files to identify changes.
- ✓Data Extraction: Use JSONPath to extract specific fields from large JSON documents.
- ✓Code Review: Format minified JSON to readable form for code review and analysis.
JSON Best Practices
Use Double Quotes
JSON requires double quotes for keys and string values. Single quotes are not valid.
No Trailing Commas
Unlike JavaScript, JSON does not allow trailing commas in arrays or objects.
Valid Data Types
JSON supports: objects, arrays, strings, numbers, booleans, and null.
No Comments
Standard JSON does not support comments. Use JSON5 or remove comments before parsing.
Frequently Asked Questions
Is my JSON data secure?
Yes! All processing happens entirely in your browser. Your JSON data is never sent to our servers or stored anywhere. This makes it safe for sensitive data like API keys or personal information.
What is JSONPath and how do I use it?
JSONPath is a query language for JSON, similar to XPath for XML. Use expressions like "$.users[0].name" to extract specific values. Start with "$" for root, then use dot notation for properties and brackets for array indices.
How does the JSON Compare feature work?
The Compare feature performs a deep comparison between two JSON objects and shows all differences including added, removed, and modified fields. Different change types are color-coded for easy identification.
What is the maximum JSON size?
There is no strict size limit, but very large JSON files (over 10MB) may cause performance issues in your browser. For extremely large datasets, consider processing them in smaller chunks.
When should I use Escape/Unescape?
Use Escape when you need to embed JSON inside a JavaScript string or store it in a database. Use Unescape to convert escaped JSON back to its original form.
