View and edit JSON in a clean, spacious editor

See file name, size, and character count at a glance

Line wrapping and indentation keep complex data readable

Convert and transform JSON in one tap

Format / pretty‑print compact or messy JSON

Minify JSON when you need compact output

Sort keys for consistent structure

Change case conventions to match your style

Validate JSON and catch errors before you ship

All operations are optimized for real‑world payloads, so even big files stay responsive on a modern device.

Load JSON from file or URL

Load JSON or text files from device storage (up to 10 MB)

Import JSON directly from a URL (API endpoints, raw .json links, etc.)

Quickly re‑load recent URLs from history

This makes JSON Pro Essentials a great companion for API testing, debugging, and exploring live data.

See structure clearly with Branched view

Explore JSON as a structured tree

Inspect objects and arrays without losing your place

Switch between the editor and Branched view as needed

Branched view is ideal for understanding unfamiliar JSON, even if you prefer to edit in the main editor.

Customize your workspace

Choose from multiple fonts and sizes for comfortable reading

Pick from curated themes or create your own

Edit theme JSON directly for full control

Use the advanced color picker (hue, saturation, luminosity, alpha) to fine‑tune every detail

Themes are JSON‑based, so they’re easy to tweak by hand or even generate with your favorite AI tools

You can keep things subtle or build a bold, high‑contrast theme that fits how you work.

Designed for developers and power users

JSON Pro Essentials: Editor is built for people who live with JSON every day:

Mobile and backend developers

QA and test engineers

DevOps and SREs

Data and API enthusiasts

If you’ve ever wished your phone had a serious JSON tool instead of a basic viewer, this app is for you.
