Paste raw JSON and instantly see a formatted, color-coded, collapsible tree — validate and debug in one tap. Paste raw JSON and read it instantly — formatted, color-coded, and collapsible. JSON, made readable. Paste a minified blob and JSON Viewer pretty-prints it with clean indentation in an instant. Color-coded clarity. Keys, strings, numbers, and booleans each get their own color so structure jumps out at you. Collapse the noise. Fold deep objects and arrays to focus on exactly the branch you care about. Catch broken JSON. Invalid syntax is flagged with the line and reason — fix malformed payloads fast. Private by design. Your JSON never leaves the device. No accounts, no servers, no tracking — ever. — SUBSCRIPTION — Premium unlocks all features. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Manage or cancel anytime in App Store settings.
