Frequently Asked Questions

Everything you need to know about ViewJSON

Is my data safe?

Absolutely. ViewJSON processes everything locally in your browser. Your JSON data never leaves your device or gets uploaded to any server.

How does sharing work?

When you share, your JSON content is compressed and encoded directly into the URL—nothing is uploaded to any server. Recipients open the link to instantly view your data.

How do I save my work?

ViewJSON automatically saves your JSON to browser history. Click the sidebar icon to view and restore previous versions anytime.

What are variables?

Variables let you insert named placeholders for dynamic values. Perfect for parameterizing API tokens, environment URLs, or test data.

What do variable colors mean?

Variable badges are color-coded by type: red for strings, green for numbers, blue for booleans, and gray for null. This helps you spot types at a glance.

How does the API Request Builder work?

Enter a URL and customize HTTP method, headers, and body. Copy your request as cURL or HTTP format for use in terminal or other tools.
