❓ Frequently Asked Questions
JSON (JavaScript Object Notation) is a lightweight data format used to store and exchange data, especially in web APIs.
Common issues include missing quotes around keys, trailing commas, or single quotes instead of double quotes.
Format adds indentation for readability; minify removes all whitespace to reduce file size.
