About
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.
