Useful errors
Invalid JSON is reported with the browser's parsing message and, when available, line and column.
No account
Use it immediately and leave. There is no signup, token allowance or usage limit.
Format JSON safely online
Paste JSON into the input and choose Format & validate. Use Minify when you need a compact payload, or sort keys to make two objects easier to compare. All values are preserved according to the JSON standard.
Common questions
Does RWAVE store my JSON?
No. The contents stay in this browser tab. Anonymous analytics record that the tool completed, never the pasted text.
Can this fix malformed JSON?
It identifies invalid syntax but does not guess a correction, because an automatic guess can silently change your data.
