About the JSON Formatter
Pretty-print, indent and validate any JSON document. Spot syntax errors at a glance and copy the formatted output straight into your code.
Useful for debugging API responses, configuration files and structured data feeds.
How it works
- Paste raw JSON.
- Read the pretty-printed output, or the error message if it is invalid.
- Copy the formatted JSON.
What you'll learn
- Common JSON syntax errors (trailing commas, unquoted keys).
- Why pretty-printed JSON is easier to diff and review.
FAQs
- Will it fix invalid JSON?
- No. It validates and reports errors, but does not silently repair broken syntax.
