What is a JSON Tree Viewer?
A JSON Tree Viewer renders JSON data as an interactive, collapsible tree structure — making it easy to explore deeply nested objects, arrays, and values at any depth. Paste your JSON and navigate the structure visually.
Frequently Asked Questions
A JSON formatter just pretty-prints JSON with indentation. A tree viewer renders it as an interactive visual hierarchy — you can collapse/expand nodes, search within values, and inspect data types at a glance without counting brackets.
No — all rendering happens in your browser using JavaScript. Your JSON data never leaves your device.
The tree viewer handles most real-world JSON files well up to ~2MB. For very large files (10MB+), consider using a desktop tool like VS Code or jq for better performance.
Colors indicate data types: strings are shown in green, numbers in blue, booleans in orange, and null values in gray — making it easy to spot the type of each value at a glance.
