About JSON URL Encoding

URL encoding converts special characters in JSON data to percent-encoded format. This ensures JSON can be safely included in URLs, query parameters, and form submissions without breaking the URL structure.

Common Encoded Characters

" → %22
{ → %7B
} → %7D
[ → %5B
] → %5D
: → %3A
, → %2C
Space → %20

Use Cases

  • Query string parameters in URLs
  • Form data submission
  • URL fragments and hash parameters
  • API endpoint parameters
  • HTTP header values
  • Cookie values with JSON data
  • POST request body encoding
  • Webhook payload transmission
