Privacy details

JSON tree viewer processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Your result

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

JSON tree viewer explained

View a text tree of JSON types, values and JSON Pointer paths. Container lines show their immediate child count; leaf lines show the actual value. This makes nested data easier to locate without flattening away arrays or nulls.

Next: JSON Schema validator

Next: JSON diff

A worked example

In {"a":[1]}, the number 1 appears at /a/0. A key containing a slash is escaped with ~1 in its pointer path.

Before you use the result

The tree is a read-only outline, not a schema validator. Keys and arrays keep their original order. Large exact numeric IDs must be quoted.
