What is JSON (JavaScript Object Notation)?
JSON (RFC 8259) is an open standard, lightweight data-interchange format designed for human readability and easy machine parsing. It has become the ubiquitous standard for REST APIs, modern web services, and configuration files.
Secure Browser-Side Processing
Many online JSON formatters transmit your payloads across the internet to be parsed by back-end servers, exposing API tokens, passwords, or customer data to potential logging. Utilivox executes JSON formatting entirely inside your local browser JavaScript engine using native JSON.parse() and JSON.stringify(), ensuring 100% data confidentiality.
Mathematical Formula
Step-by-Step Worked Example
Input: {"a":1,"b":[2,3]}
Formatted:
{
"a": 1,
"b": [
2,
3
]
}
Important Considerations & Limitations
All keys in standard JSON must be enclosed in double quotes. Single-quoted strings or trailing commas will trigger a syntax validation error per the JSON specification.
