Frequently Asked Questions
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data format used for storing and transmitting data between a server and a web application. It uses human-readable text in key-value pairs.
Why validate JSON?
Invalid JSON causes API errors and parsing failures. Common mistakes include trailing commas, unquoted keys, and single quotes instead of double quotes.
When should I minify JSON?
Minification removes whitespace and reduces file size. Use it for production API responses to reduce bandwidth and improve performance.
