A very good tool, the ads are also placed in such a way that it doesn't affect the users.

I use Format JSON Online almost daily, it's fast, clean, and privacy-friendly. Makes formatting, validating, and comparing JSON effortless. Love it!

The response was very prompt, results appeared immediately after pasting the text. The page is also very clean and could completely replace my local JSON tool software.
