Format Express is the quickest formatter in town, with tons of features : just paste, and JSON / XML / SQL is immediately beautified in a viewer with syntax highlighting, node navigation, minimap, search with regular expression, recursive formatting, ...

Enjoy, it's free, intuitive and very fast. Format JSON (or similar), format XML, format SQL, format anything !

Is this a JSON / XML / SQL validator ?

No, it's not a validator. The formatter is very tolerant and accepts anything that looks like JSON / XML / SQL. Moreover, if the input is invalid or truncated or escaped, Format Express may even try to fix it and unescape it. In these cases, the result may not be strictly equivalent to the given input.
The most common use-case is to help reading minified input found in logs or web services.

Tell me about privacy. Is my data safe ?

Yes. The data submitted on this site is securely sent over https to the server for the formatting, where it is neither saved nor logged.

How can I trust you ?

You can't ! So if your data contains sensitive or personal information, do not submit it on any random website, including this one.
