JSON Viewer - View, Format, Query & Convert JSON Online

What is JSON Viewer?

JSON Viewer is a free, feature-rich online tool designed to help developers, data analysts, and anyone working with JSON data. Whether you need to quickly format messy JSON, search for specific values, or convert your data to other formats, this tool has everything you need in one place.

Key Features

View & Format JSON

Paste your JSON data and instantly view it in a clean, collapsible tree structure. Switch between tree view, code view, and read-only modes. Use the Beautify button to format your JSON with proper indentation, or Minify to compress it into a single line for production use.

JSON Statistics

Get instant insights about your JSON structure. The statistics panel shows you the total number of keys, values, maximum nesting depth, original and minified file sizes, plus a breakdown of data types (strings, numbers, booleans, arrays, objects, and nulls).

Search Within JSON

Looking for a specific value buried deep in your JSON? Use the Search tab to find matches by keys, values, or both. Each result shows the exact path to the data, which you can copy with a single click.

JSONPath Query

Run powerful JSONPath expressions to extract exactly the data you need. Supports standard JSONPath syntax including wildcards ($..name), array access ($.users[0]), and filter expressions ($.items[?(@.price<100)]).

Convert to Other Formats

Transform your JSON data into other popular formats with one click:

• YAML - Human-readable configuration format
• XML - Standard markup language for data exchange
• CSV - Spreadsheet-compatible format for tabular data

Compare Two JSON Objects

Need to spot differences between two JSON files? The Diff tab lets you compare them side by side. It highlights what was added, removed, or modified, with exact paths to each change.

JSON Schema Validation

Validate your JSON data against a JSON Schema to ensure it meets your requirements. The validator checks data types, required fields, minimum/maximum values, string patterns, and more. Clear error messages help you fix any issues quickly.

Load JSON from URL

Working with an API? Simply paste the URL and fetch JSON directly from any public endpoint. The tool automatically formats the response for easy viewing.

Download & Export

Export your data in multiple formats: formatted JSON, minified JSON, YAML, XML, or CSV. Perfect for saving processed data or sharing with teammates.

Copy Path & Copy JSON

Click any node in the tree view to see its JSONPath. Use the Copy Path button to grab the exact path for use in your code. The Copy button saves the entire formatted JSON to your clipboard.
