Treeflux

Treeflux is a fast, offline JSON toolkit built for developers who work with JSON
every day — Android engineers, backend and API developers, QA testers, and students
alike.

Paste, open, or drop in a JSON file and Treeflux takes care of the rest: beautify it
with configurable indentation, minify it for production, validate it with precise
line-and-column error reporting, or explore it as an interactive, expandable tree.

JSON Formatter
Beautify messy JSON into clean, readable output, or minify it down for transport —
in one tap. Copy, share, or save the result straight from the toolbar.

JSON Validator
Real-time validation as you type, with the exact line and column of the first syntax
error so you can fix it immediately — no more hunting through a wall of text.

Interactive Tree Viewer
Expand and collapse nodes, search by key, value, or type (object, array, string,
number, boolean), and copy any node's JSON straight from the tree. Parent and child
highlighting make it easy to understand nested structures at a glance.

Import & Export
Open JSON files from anywhere on your device and save your results back out, using
Android's built-in file picker — no special storage permission required.

Offline & Private
Treeflux never asks for the INTERNET permission and has no analytics or ad SDKs.
Every byte of JSON you work with stays on your device, in History and Favorites you
control completely.

Performance
Built natively in Kotlin and Jetpack Compose with a tree model designed to stay
responsive even on large JSON files.

Accessibility
Content descriptions, adequate touch targets, and a high-contrast dark interface
designed for long developer sessions.

Why developers choose Treeflux
A single, focused tool that replaces switching between a text editor, an online
formatter, and a validator website — all without sending your data anywhere.
