FAQ – JSON Formatter & Validator

Why does my JSON fail to parse?

Common issues: trailing commas, single quotes, comments, or unescaped characters. JSON requires double-quoted strings and no comments.

Can I format huge files?

Yes, within your browser’s memory limits. For very large files, consider splitting them first.

Does the tool support JSON5 or comments?

No. It follows strict JSON. Remove comments/trailing commas before validating.
