Frequently Asked Questions
What is a JSON Formatter?
A JSON formatter takes raw JSON text and pretty-prints it with indentation so it is easier to read. It can also minify JSON into a single line and validate whether the syntax is correct.
Is my JSON uploaded to a server?
No. Formatting and validation run entirely in your browser. Your JSON never leaves your device.
Can I sort object keys?
Yes. Turn on Sort keys to alphabetically order keys in JSON objects, which is useful for diffs and consistent API payloads.
