How to Use the JSON Validator Pro

Welcome to the ultimate client-side JSON tool. Whether you are a developer, data analyst, or student, this tool helps you clean, debug, and visualize JSON data efficiently.

Key Features

• Validation: Instantly check if your JSON is syntactically correct according to RFC 8259 standards.
• Formatting (Pretty Print): Convert minified or messy JSON strings into a clean, readable hierarchy with proper indentation.
• Minification: Compress your JSON by removing whitespace to save bandwidth or storage space.
• Smart Fix: The tool attempts to fix common errors such as trailing commas, single quotes instead of double quotes, or missing quotes around keys.
• Tree View: Explore deep nested objects with an interactive collapsible tree visualization.

Step-by-Step Guide

1. Input Data: Paste your JSON code into the left editor panel. You can also click the "Sample" button to load test data.
2. Validate: Click the blue "Validate & Format" button. If the JSON is valid, it will be formatted in the right panel. If invalid, an error message will appear highlighting the line number and specific syntax error.
3. Fix Errors: If you receive an error, try the "Smart Fix" button to see if the tool can auto-correct syntax issues.
4. Visualize: Toggle between "Code" and "Tree" view in the right panel header to explore your data structure.
5. Export: Use the Copy button to grab the processed JSON or the Minify button to compress it before copying.
