KITFORMA · EDITORIAL ANSWER
Why is my JSON rejected even though it looks like JavaScript?
KitForma editorial guide. JSON is a data format with stricter syntax than a JavaScript object literal. Formatting cannot repair an unknown intended value automatically.
Step-by-step answer
In https://kitforma.com/en/json-formatter/, quote property names and string values with double quotes. Remove comments and trailing commas; use lowercase true, false and null. For example, {"name":"Ada","active":true} is valid JSON.
If a string contains a quote or line break, encode it correctly rather than placing an unescaped newline inside the string. Check the reported error near the surrounding value, not just the highlighted character.
The formatter changes whitespace while preserving number literals, member order, duplicate keys and string escapes. Duplicate keys may still be interpreted differently by another application, so avoid them for interoperability. Nesting is limited to 100 levels and non-finite numeric ranges are rejected. Replace API keys and personal data with placeholders before posting a sample.
