JSON (JavaScript Object Notation) has become the universal format for APIs, applications, and structured SEO data. But large or unformatted JSON can be difficult to read, analyze, or debug. That’s where our JSON Viewer helps.

This tool allows you to paste or load JSON and instantly view it in a clean, structured format. With advanced viewing options, it becomes easy to search, navigate, and analyze JSON data.

How the JSON Viewer Works

You can open JSON data in two simple ways:

Enter a URL → load JSON directly from a web resource.
Paste JSON → copy and paste JSON into the editor.

Click View JSON and results appear instantly inside an interactive editor where you can:

Switch Views → choose between code, form, text, tree, or view mode.
Use Search → quickly locate specific keys or values.
Export → either save the formatted JSON as TXT or copy it to clipboard.

This makes it simple to analyze JSON of any size, whether from an API or structured SEO data.

Why Use a JSON Viewer?

Readability: Transform raw JSON into a clear, structured layout.
Analysis: Search through JSON data to find what you need quickly.
Debugging: Combine with the JSON Validator to check for errors.

JSON Viewer for SEO & Development

By combining this tool with others in our suite, you can:

Format JSON before analysis with the JSON Formatter.
Validate JSON-LD with the JSON Validator.
Edit structured data with the JSON Editor.

This workflow makes managing structured data faster and easier for developers and marketers.
