JSON Convert Tools

JSON Viewer

Explore JSON objects and arrays in a collapsible tree.

Local processing

Drop a file here, or paste your data. Maximum 10 MB. Text files must use UTF-8.

Ready when you are.

Your data is processed in your browser and is not stored on our servers.

JSON numbers use JavaScript precision. Quote large identifiers to preserve their digits. Duplicate object keys keep the last value.

What is JSON Viewer?

Explore JSON objects and arrays in a collapsible tree.

A collapsible tree separates arrays, objects and scalar values. Expand a branch to inspect a field without scanning an entire document.

Why use JSON Viewer?

Use this tool to inspect a small dataset or prepare data for another application without installing software. Processing takes place in this browser. No account is required.

How to use JSON Viewer

  1. Paste your input, upload a file, or load Sample Data.
  2. Choose any applicable options and select View.
  3. Review the output, then copy or download it.

Example

Input

{"user":{"name":"Ada","roles":["editor"]}}

Output

Expandable user object containing name and roles.

Common problems

To keep the page responsive, the tree preview is capped at 2,000 nodes. The full parsed JSON remains available in the output and download. Avoid using sensitive data on a shared device.

Frequently asked questions

Is my conversion data uploaded?

No. Conversion inputs and outputs remain in this browser. Contact form messages are handled separately by WordPress.

Can I process large files?

The default limit is 10 MB. Browser memory and data complexity can impose lower practical limits.

Do I need an account?

No account is needed to use this tool.
