Place your JSON into the left text field and click to update it. The output will be placed in the right text field for easy copying. While this tool does check for valid JSON, it will not provide detailed reports. For detailed validation, use the main JSON editor.
Formatting text for use with JSON can be kind of a pain, so this tool can do it for you. This should work for all text such as CSS, Regular Expressions, and anything else. Regular text goes on the left, encoded text goes on the right.
