The Problem
You open an API endpoint in the browser. Wall of unformatted JSON. You copy it, open a new tab, paste it into a formatter, wait, read, go back. Repeat this a dozen times a day and it quietly steals hours from your week.
What It Does
JSON Modal Viewer & Formatter keeps you in your flow. No tab switching. No copy-pasting. JSON goes from unreadable to instantly navigable, right on the page you're already on.
Auto-Detection
Open any URL that returns raw JSON (API endpoints, REST responses, log URLs) and the extension detects it automatically. Inline buttons appear next to JSON blocks. A floating action button sits in the corner, always ready.
Works with dynamically loaded content too, including SPAs and lazy-loaded payloads.
Select Any JSON, Anywhere
Found a JSON snippet buried inside a log, a dashboard, or some documentation? Select the text. A small {} icon appears near your cursor. One click opens a formatted, highlighted modal, no clipboard gymnastics required.
A Viewer Worth Using
JSON opens in a professional editor powered by CodeMirror:
- Syntax highlighting
- Line numbers
- Code folding
- Active line highlighting
- Automatic formatting
- Handles payloads up to 1MB
Large, deeply nested objects become readable in seconds.
Copy in Any Format
Need to share it? Grab the JSON in whichever shape you need:
- Pretty-printed: indented and human-readable
- Minified: compact, ready to paste into code
- Original: exactly as the source provided it
Your Preferences, Instantly Applied
Light, Dark, or System theme. Auto-detection and selection tooltip toggle independently. Every change takes effect on the current page immediately, no refresh, no fuss.
Your Data Stays Yours
The extension only uses storage permission to save your preferences. Nothing is collected, transmitted, or shared. All processing happens locally in your browser.
If you work with APIs, logs, or admin panels and raw JSON is part of your daily life, install it and never open a formatter tab again.
