JSON Viewer

Interactive tree view for exploring JSON data structures

About This Tool

Use the JSON viewer when a payload is valid but too nested to inspect as plain text. The expandable tree keeps objects, arrays, scalar values, and nesting depth visible so API responses, state snapshots, configs, and webhook payloads are easier to navigate.

Viewer Sample: Inspect A Checkout Response

Real input sample
{
  "order": {
    "id": "ord_1001",
    "status": "paid",
    "customer": { "id": "cus_24891", "tier": "pro" },
    "items": [{ "sku": "pro-plan", "quantity": 1 }]
  }
}
Expected output review

The tree opens with root.order visible, shows order.customer as an object, items as a one-row array, status as a string, and quantity as a number you can copy from its node.

Common error states
  • A trailing comma after the items array prevents the tree from rendering.
  • A log line wrapped around the JSON must be removed before parsing.
  • Stringified nested JSON appears as a string until you unescape and parse it separately.
Next checks
  • Use JSON Parser to create a path table for order.customer.tier.
  • Use JSON Path Finder when you need to extract only the items array.
  • Use JSON Compare if the same response changed between staging and production.

Local processing: This JSON work happens in your browser after the page loads. Redact secrets, tokens, emails, and customer identifiers before sharing copied output.

Interpreting the Tree

Expand from the root to understand the response envelope, then drill into the object or array that owns the field you care about. If a node displays as a string but looks like JSON, it is probably escaped nested JSON and should be unescaped before deeper inspection.
