About JSON Formatter

This extension improves the readability of JSON responses by rendering them as a structured, collapsible tree. It helps you scan complex data and locate fields quickly—ideal for API debugging, data verification, and everyday development workflows. Raw mode is always available, so you can instantly return to the browser’s default JSON view when needed. Multi‑Theme Support Includes multiple built‑in themes (Classic / VSCode / GitHub / Claude / Google), switchable from the Options page or the popup menu.
