When to use a JSON viewer instead of a formatter
A JSON formatter gives you indented text. A JSON viewer gives you an interactive tree. The distinction matters when:
- The payload is deeply nested and you need to collapse branches to focus on one part.
- You're searching for a specific key or value inside a large response.
- You need to copy the JSON path to a field — for use in code, JQ queries, or JSONPath expressions.
- You want to see types at a glance: is that
"123"a string or a number?
If you just need to pretty-print and copy, use the formatter. If you need to explore, navigate, and understand structure, use this viewer.
Features of this JSON viewer
- Collapsible tree — expand and collapse any object or array node. The Expand/Collapse button toggles all nodes at once.
- Type indicators — every node shows its JSON type (string, number, boolean, null, object, array) in a color-coded badge.
- Path copying — click any key to copy its dot-notation path (e.g.
users[0].address.city) to your clipboard. - Search — type in the search box to filter the tree by key names or values. Only matching branches are shown.
- Stats bar — see the total number of nodes, maximum nesting depth, and payload size at a glance.
Common use cases for a JSON viewer
Developers reach for an online JSON viewer in a few recurring situations:
- API debugging — paste a REST or GraphQL response and navigate the tree to find the field you need.
- Config inspection — open a
package.json,tsconfig.json, or Terraform state file to quickly locate a setting. - Data exploration — when you receive a JSON dataset and need to understand its shape before writing code.
- Path extraction — click a key to copy its path, then paste it into your code, a JQ filter, or a JSONPath query.
