}About JSON Viewer
Raw JSON crammed onto one line is nearly impossible to read, and a missing bracket can hide deep inside the mess. The JSON Viewer turns that tangle into an interactive tree you can expand and collapse, letting you navigate nested objects and arrays by clicking instead of scrolling through a flat blob of text.
Paste your JSON and the tool lays out its structure so you can drill into exactly the part you care about and fold away the rest. It runs in your browser, free and instantly, with no signup required. Nothing you paste is stored, so you can inspect API responses, config files, or data payloads privately and skip the watermarks and limits other viewers tend to add.
Common uses
- Exploring an API response to find a specific field deep in the structure
- Reading a config or settings file that's hard to follow as plain text
- Checking the shape of nested data while debugging code
- Verifying a JSON payload before sending or saving it
- Collapsing large sections to focus on the part of the data you need

FAQ
Does it validate my JSON too?
Its main job is to display valid JSON as a navigable tree. If the data can be parsed, you'll be able to explore it; broken JSON won't render as a tree.
Can I edit the JSON here?
It's built for viewing and exploring structure rather than editing. You browse the tree to understand the data.
Is my data kept private?
Yes. The tool doesn't store what you paste, so you can inspect sensitive payloads without it being saved anywhere.
Can I use JSON Viewer on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
