What is the JSON Validator?

JSON Validator scans raw text against standard JSON parsing rules. If it encounters syntax violations (such as missing braces or trailing commas), it rejects the structure and outputs a pinpoint error reference.

Frequently Asked Questions (FAQ)

Q: Why is my JSON invalid?

Common issues include using single quotes instead of double quotes, trailing commas after the last item, or comments.
