JSON Viewer
Explore JSON as a collapsible, color-coded tree.
Why use this viewer
Collapsible tree
Expand or collapse any object or array node individually, or all at once.
Color-coded types
Strings, numbers, booleans, and null are each colored distinctly for fast scanning.
Item counts while collapsed
Collapsed nodes show how many keys or items they contain, so you know what's inside before opening it.
Handles deep nesting
Built to stay responsive on deeply nested API responses and configuration files.
About the JSON Viewer
Paste JSON and instantly browse it as a navigable tree — expand and collapse objects and arrays, see item counts at a glance, and scan large documents without scrolling through raw text.
