Format JSON Online is a fast, free, and privacy-focused tool to format, validate, minify, and beautify JSON data directly in your browser. Built for developers and API testers, it offers support for large JSON files without requiring login or sending data to a server. Additional features like JSON-to-CSV, JSON-to-XML, and cURL conversion make it a versatile tool for debugging, transforming, and visualizing JSON. Light ads may be introduced in the future to support development, but user privacy and experience will always be top priorities.
Codacy automates code reviews and monitors code quality on every commit and pull request reporting back the impact of every commit or pull request, issues concerning code style, best practices, security, and many others. It monitors changes in code coverage, code duplication and code complexity. Saving developers time in code reviews thus efficiently tackling technical debt. JavaScript, Java, Ruby, Scala, PHP, Python, CoffeeScript and CSS are currently supported. Codacy is static analysis without the hassle.
