Frequently asked questions
What does a JSON formatter do?
A JSON formatter turns unformatted JSON into a readable, indented structure, so you can see nested objects and arrays at a glance – ideal for debugging API responses.
What is the difference between formatting and minifying?
Formatting adds indentation and line breaks to make JSON readable. Minifying removes all unnecessary whitespace to reduce the file size – useful in production.
Can I convert JSON to CSV?
Yes. The tool converts JSON arrays of objects to CSV. The object keys become the column headers – perfect for importing into Excel or Google Sheets.
Are syntax errors detected?
Yes. For invalid JSON you see the exact error message, e.g. a missing quote or comma, so you can find and fix mistakes quickly.
Is the JSON formatter safe?
Absolutely. All processing happens locally in your browser. Your JSON is never sent to a server – fine for sensitive data too.
