Working with JSON is an unavoidable part of development today — whether you’re building APIs, integrating third-party services, or debugging data. While modern editors offer basic JSON support, dedicated tools can significantly speed up your workflow and reduce errors.

Here are 6 must-try JSON tools that every developer should have bookmarked 👇

🧼 1. FormatJSONOnline.com

A clean, ad-free JSON formatter and validator you can use without any distractions. It handles formatting, validation, and even minification in a single click — all in the browser.

🔹 No ads

🔹 Lightning fast

🔹 Mobile-friendly

If you're tired of bloated tools or copy-pasting into formatters filled with popups, this one is for you.

🧰 2. JSON Formatter Chrome Extension

This browser extension highlights and formats JSON directly when opening .json files — ideal for debugging APIs on the fly.
