- Great Extensions The one of the most useful stuff found on internet
- Asifur Rahman
- This JSON formatter is a clean tool that does exactly what you need by running locally so no sensitive tokens or credentials ever leave your computer. The auto paste from clipboard is such a nice touch because your data is already there the moment you open the extension while the tree view makes navigating messy nested responses super helpful. It cleans up messy data fast and makes everything easy to read which is essential when you are working with API responses all day. Anyone who deals with JSON will find this simple and reliable tool very useful for their daily workflow.

- This helps me validate, edit, and beautify JSON in one click, the most powerful JSON tool on chrome.JSON fommerter runs 100% localy, as my data never leaves my browser, no server, no tracking, no risk. why i choose this over the others is that I get more than a viewer, as I can format, validate, minify, convert, and diff JSON. It has 100% local processing, as my API keys, tokens, and config data stay safe

- Finally stopped pasting API responses into random online formatters. The fact that everything runs locally is a huge deal when your working with tokens and credentials all day. Auto-paste from clipboard is such a nice touch, just open it and your JSON is already there. Tree view is super helpful for navigating messy nested responses too. Clean tool, does exactly what you need.

- Lazar Antic
- I’ve been using JSON Formatter Pro for handling raw JSON data, and it’s been a great addition to my workflow. It instantly formats messy JSON into a clean, readable structure, which makes debugging much easier. I also like how fast and responsive it is. Simple, reliable, and very helpful for anyone working with APIs or structured data regularly.
- Gimme Video
- Handy JSON tool for developers who work with APIs regularly. The formatting is instant and the syntax highlighting makes it easy to spot structure at a glance. I really like the validation feature that points out exactly where a JSON error is located rather than just saying it is invalid. The compare mode is useful when debugging response differences between environments. Everything runs locally in the browser which is important when working with sensitive data. The side panel integration keeps the formatter accessible without switching tabs. Clean and focused utility that does its job well.
