Frequently Asked Questions
What's the difference between this and the JSON Formatter?
This tool focuses purely on checking validity and reporting errors. The JSON Formatter also beautifies or minifies valid JSON.
Why does my JSON fail even though it looks correct?
Common issues include trailing commas, single quotes instead of double quotes, or unescaped special characters — all of which are invalid in strict JSON.
