Frequently asked questions
How do I fix "Unexpected token" errors in JSON?
Paste the JSON here and press Validate. The error message names the exact character position, which is almost always a trailing comma, a single quote instead of a double quote, or an unquoted key.
Does this JSON formatter upload my data?
No. Parsing and formatting happen in your browser, so the JSON never reaches our servers.
