What is JSON Formatter?
"JSON Formatter" is a user-friendly Chrome extension designed to simplify the reading of JSON by automatically formatting it when loaded in a browser. It offers convenient features such as syntax highlighting, collapsible trees with indent guides, clickable URLs, and a dark mode. Despite its feature richness, it has negligible performance impact on non-JSON pages. Moreover, it respects user privacy with no tracking or advertisements.
