Frequently asked questions

When do I need to escape JSON?
When embedding a JSON string inside another JSON document, a database column, or a programming-language string literal, special characters like quotes and newlines must be escaped.
Does it handle unicode characters?
Yes. Escaping preserves unicode and can optionally output \u escape sequences; unescaping restores the original characters.
Is my data uploaded to a server?
No. Every tool on JSONPost runs entirely in your browser using JavaScript. Your JSON never leaves your device, so it is safe to use with private or sensitive data.
