🔗 JSON URL Decoder — Free Online Tool

Decode URL-encoded strings back to JSON objects instantly with our free online JSON URL Decoder. Converts URL-safe strings to valid JSON — all processing happens in your browser.

🚀 What Is JSON URL Decoding?

JSON URL decoding reverses JSON URL encoding by:

First URL-decoding the string using decodeURIComponent()
Then parsing the JSON string using JSON.parse()

This is useful when you need to extract JSON data from URL parameters or query strings.

For example:

Input: %7B%22name%22%3A%22John%20Doe%22%2C%22age%22%3A30%7D
Output: {"name": "John Doe", "age": 30}
