JSON Formatter

Great free code formatter.

Best JSON formatter extension among the ones I've used. My eyes won't hurt anymore trying to figure out which bracket ends where when testing APIs directly on browser lol

Hey William, thanks for flagging this! We were experimenting with analytics to help us identify crashes and improve stability. We've rolled this back in v2.1.17, which is now live and being rolled out. Going forward, we'll ensure any analytics collection is clearly disclosed. Thanks again!

Does exactly what it says. Clean formatting, tons of themes, and the collapsible sections in parsed mode are super useful for digging through big API responses. No complaints!

Does exactly as described - far better than the more popular alternative, which recently started asking for donations in popups

There is no option to collapse and expand all. By default all of them are expanded which is very annoying.

Hey! Thanks for the review Sorry to see you faced an issue But the feature is already present, and you can configure their hotkeys as well! by default pressing the `[` key will collapse all, and `]` key will expand all, you can change the keys to your preference by editing them from hotkey option in the extension options. If you prefer right click menus, you can enable them from the extension options and then collapse and expand from the right click menu. Hope you reconsider your review 🙂

Hello, I think some of the Json formats were misinterpreted when using 'Parsed'. What are you doing using the keyword 'tsource' or 'Domain' format? For example, "https://www.example.com?tag=bbb&tsource=www.aaa.com&token=aaa" It needs to be parsed like this "www.aaa.com&token=aaa" target="_blank">https://www.example.com?tag=bbb&tsource=www.aaa.com&token=aaa" It's parsed like this. In 'Formatted Raw' or 'Raw', it is displayed normally.
