What is JSON Viewer, Formatter & Validator?

JSON (JavaScript Object Notation) is the standard data interchange format used across modern web development, mobile applications, cloud services, and RESTful APIs.

Often, API responses and raw logs are returned minified onto a single line or contain minor syntax errors (such as trailing commas, single quotes, or missing closing brackets) that make them impossible to read, debug, or parse. Apnu Gujarat Job's JSON Viewer & Formatter provides an all-in-one developer workspace to format, validate, inspect interactive tree hierarchies, edit syntax with instant repair, and export data into multiple formats seamlessly.

Key Features:

• ⚡ 2 & 4 Space Beautifier: Instantly transform minified or unformatted JSON into cleanly indented, human-readable code with accurate line counting.
• 🗜️ 1-Click Minifier: Strip unnecessary whitespaces, line breaks, and indentation to produce ultra-compact payloads optimized for network transfer.
• 🌳 Interactive Tree Visualizer: Browse deep nested objects and arrays with collapsable nodes, visual type tags (string, number, boolean, null), and 1-click JSON path copying.
• 🔧 Smart Syntax Auto-Fix: Automatically repairs common JSON errors including single quotes, trailing commas, unquoted keys, and unclosed brackets.
• 📊 High-Performance Table View: Automatically detects tabular array data and presents it in a searchable, paginated data grid capable of handling thousands of rows without browser lag.
• 🔄 Multi-Format Converters:
  • JSON to CSV / Excel: Export structured tabular datasets directly into spreadsheet-ready CSV files.
  • JSON to XML & YAML: Convert payloads for server configuration and cross-platform integrations.
  • JSON to TypeScript & PHP: Auto-generate typed interfaces and associative array definitions for frontend and backend codebases.
• 🔒 100% Client-Side Privacy: Your data is processed entirely within your local browser runtime. Zero data, sensitive payloads, or API tokens are ever transmitted or stored on any server.

How to Use This Tool:

1. Paste or type your JSON in the Text tab, or use the Upload button to load a .json file up to 25MB.
2. Click Format to beautify, or click Auto-Fix if syntax errors are detected.
3. Switch to the Viewer tab to explore data hierarchically, or Table tab to view array records.
4. Use the Copy or Download buttons to save your formatted code or exported CSV/XML files.
