JSON Tree view

Deep responses still need a lot of scrolling after Format. Tree view lays paths out by indent.

Paste JSON, click Generate tree view, and the right pane shows keys and type hints as text.

It is a reading aid, not a collapsible editor. Use JSONPath when you need an exact value.

Preview is generated locally. Large objects depend on browser memory.

How this shares work with Format

Format gives you copyable valid JSON. Tree view helps you count levels and find which layer a field sits on. It does not change values.

After you find the path

Once you see users / 0 / email, write $.users[0].email in JSONPath or NL Query.

How to use it

  1. Paste JSON, or load a sample.
  2. Click Generate tree view.
  3. Find fields by indent and note the path.
  4. Use JSONPath to extract; use Format to edit text.
  5. Object arrays can also be scanned by column on the Table page.

When to use it

  • Read a gateway wrapper that is three or more levels deep.
  • Show a new teammate where a field lives.
  • Learn the road before you write JSONPath.
  • Switch presentation when Format still makes your eyes glaze over.

Keep in mind

  • You cannot edit on the tree.
  • A few MB is usually fine. Trim larger files first.
  • Nothing is uploaded.

FAQ

Can I edit values on the tree?

This page is a preview. Change values in the input or on the Format tool.

Will a large JSON stall?

A few MB is usually fine. Huge files belong on a CLI, or trim them first.

When should I use Table instead?

Use Table for arrays of objects. Use Tree for deep nested objects.

Is it uploaded?

No.

Are types labeled?

You get type hints. Exact styling follows the output text.

Can I collapse nodes?

This is a text tree, not an IDE-style collapsible control.

How do I read array indexes?

They are listed in order. Use the index in JSONPath when you need a value.

Does this relate to Schema?

Not directly. Once you see the shape, generating a Schema is less likely to miss a level.
