JSON Formatter — Pretty Print

RAHMAN TECH

About this app

JSON Formatter is the fastest way to make sense of raw JSON on
your Android device. Paste or type any JSON string and the app
instantly validates it, pretty-prints it with full syntax
highlighting (keys, strings, numbers, booleans, and null in
distinct colors), and lets you explore the structure using an
expandable, collapsible tree view. Switch between formatted
output and tree view with a single tap. Minify bloated JSON
back to a single line whenever you need to copy compact data.
Long-press any leaf value in the tree to copy it to clipboard.
Zero dependencies — built entirely with Flutter and pure Dart..
