What this tool does

Converts JSON objects to GET query strings and parses GET strings back to JSON, handling URL encoding/decoding.

Steps

1. Paste JSON or a GET query into the top box.
2. Click JSON → GET or GET → JSON to convert.
3. Use Copy result or Clear as needed.

Examples

• {"name":"小明","age":18} → name=%E5%B0%8F%E6%98%8E&age=18
• q=hello%20world&lang=en → {"q":"hello world","lang":"en"}

Notes

• Duplicate keys will be overwritten in simple mode; customize if arrays are needed.
• All processing runs locally in your browser.
