What operations does the JSON formatter support?
Format (beautify), minify (compress) and validate (with line/column error location) — switchable, for quick JSON tidying and debugging.
How do I check if JSON is valid?
Paste and click Format. Syntax errors show exact line and column with highlighted positions; valid JSON formats normally.
Is online JSON formatting safe?
Safe. Data stays local in your browser, never uploaded — suitable for API responses and configs with sensitive fields.
JSON vs JavaScript objects?
JSON requires double quotes, no comments, no trailing commas and complete key-value pairs. This tool validates strictly against the standard.
What is JSON formatting best for?
Debugging API responses, checking config files, parsing log JSON, tidying DB exports and documenting API examples.
Are there limits on free use?
No. Free, no registration, large texts supported within browser performance limits.
Does formatting change the data?
No. Only indentation changes; structure and values stay identical, safe for production data.
Does it handle arrays and nested objects?
Yes — any nesting depth of objects, arrays, strings, numbers and booleans formats correctly with clear hierarchy.
