Common questions and solutions

❓ FREQUENTLY ASKED QUESTIONS

Q: What's the difference between JSON and JavaScript object?
A: JSON requires double quotes for keys, doesn't allow trailing commas, and has a limited set of data types. JavaScript objects are more flexible.
Q: Why does my JSON fail validation?
A: Common reasons: Missing double quotes around keys, using single quotes, trailing commas, comments (in standard JSON), or invalid data types like undefined.
Q: What is JSON5?
A: JSON5 is an extension of JSON that allows comments, trailing commas, single quotes, and other JavaScript-like syntax. Our tool supports JSON5 formatting.
