Basics

Getting started

JSON Parser Online is a powerful, browser-based tool for working with JSON data. Paste your JSON into the input panel and click Parse JSON to generate a structured, interactive view on the right.

Workflow

Core features

Primary action

Parse JSON

Validates and formats your JSON data with syntax highlighting. Automatically detects and reports errors with line and column numbers so you can fix issues quickly.

Advanced parsing

Eval JSON

Uses JavaScript's eval to interpret non-standard JSON-like data. Helpful when working with snippets that aren't strictly valid JSON.

Utilities

Minify

Removes unnecessary whitespace and formatting to produce a compact JSON string that's ideal for storage, logging, or transmission.

Readability

Colorize

Applies syntax highlighting to your JSON for better readability without changing the actual structure or values.

Nested data

Recursive parse

Automatically detects and parses nested JSON strings within your data. Turn this on when you receive JSON fields that themselves contain encoded JSON.

Tree view

Options

  • Show JS types · Display JavaScript data types (string, number, object, array, etc.) next to each value.
  • Show array index · Show 0-based index numbers for array elements to help you navigate large lists.
  • Recursive parse · Automatically parse nested JSON strings inside fields so deeply nested APIs become easier to inspect.
  • Expand all · Expand every collapsible section in the tree view for a full overview of your data.
  • Collapse all · Collapse the tree back to a compact view when you're done exploring.
Appearance

Settings & theming

Mode

Productivity

Tips & tricks

  • Use the search within your browser to quickly find specific keys or values in large JSON payloads.
  • Click any collapsible section to expand or collapse it and keep complex structures manageable.
  • Start with the built-in sample JSON to quickly explore how each feature behaves before pasting your own data.
  • All parsing happens locally in your browser · nothing is sent to any server unless you share a link yourself.
  • Use the share link button to send colleagues an exact snapshot of the JSON you're looking at for easier debugging and reviews.
