What is a JSON Viewer?
A JSON Viewer is a simple tool that allows you to view, format, and analyze JSON data quickly. JSON (JavaScript Object Notation) is a lightweight format used for storing and exchanging data — commonly found in APIs, configuration files, and web applications.
This JSON Viewer helps you paste or upload your raw JSON, automatically format and validate it, and search for specific values or keys. It’s perfect for developers debugging API responses or data analysts exploring structured data.
How to Use the JSON Viewer
- Paste or Upload: Paste JSON data into the left box or upload a .json/.txt file.
- Automatic Formatting: The tool automatically formats and validates your JSON.
- Search: Use the search bar to highlight keys or values instantly.
- Scroll & Read: The right box shows formatted JSON with scrolling for long data.
- Fetch from URL: Optionally, enter an online API URL to view JSON data instantly.
