Everything ReddJSON offers — from one-click JSON copying to AI-powered post generation.
The essentials that make ReddJSON indispensable for Reddit data work.
Click the { } JSON button on any Reddit post to instantly copy the full,
pretty-printed JSON response to your clipboard. The JSON includes the complete post data and all
comments.
The JSON button is styled to match Reddit's native UI perfectly — same font, same spacing, same hover effects. It looks like it belongs there because it's designed to.
Reddit uses infinite scroll and SPA navigation. ReddJSON uses MutationObserver to automatically detect and add JSON buttons to new posts as they load — no page refresh needed.
Works on both www.reddit.com (new Reddit with shreddit-post elements) and
old.reddit.com (classic Reddit with .thing.link elements). Dedicated selectors for
each.
Keep track of every JSON you've copied with powerful history features.
Your last 50 copied posts are stored in chrome.storage.local and persist across
browser sessions. Each entry includes title, subreddit, post ID, timestamp, and full JSON.
Quickly find any previously copied post by searching through titles, subreddit names, or post IDs. Debounced search for smooth performance.
Download your entire copy history as a timestamped .json file. Perfect for backups,
analysis, or importing into other tools.
View any previously copied JSON in a full-screen modal with syntax highlighting. Dark theme for comfortable reading, with a copy button for quick re-copy.
Click any history entry's title to open the original Reddit post in a new tab. Quick way to revisit the source.
Remove individual entries or clear all history with confirmation dialogs. Full control over your stored data.
Generate content from Reddit posts using AI providers.
Transform any Reddit post into a viral-ready LinkedIn post with one click. The AI analyzes the content and generates engaging professional social media copy.
