This is a JSON formatting/validation tool that provides several features to help you handle and check JSON data.
First, you can enter JSON content in the input box. This input box is a multi-line text area where you can input any amount of JSON data. Below the input box, there are three buttons: "Format," "Validate," and "Clear."
When you click the "Format" button, the website will parse the JSON content you entered and format it. The formatted result will be displayed in the "Formatted Result" area at the top of the webpage. The formatting process will indent the JSON data according to its structure for better readability.
When you click the "Validate" button, the website will check if the JSON content you entered complies with JSON syntax rules. If the content is valid, a message saying "Valid JSON format" will appear in the "Validation Result" area at the top of the webpage, and the area's style will be set to success. If the content is invalid, a message saying "Invalid JSON format" will be displayed, and the area's style will be set to error.
When you click the "Clear" button, the website will clear the content in the input box as well as the content in the formatted result and validation result areas. This will allow you to easily start a new input and operation.
Additionally, the website provides a selection box that allows you to choose the size of the indentation. You can choose 2 spaces, 4 spaces, or a tab as the indentation method. Selecting different indentation methods will affect the appearance of the formatted JSON data.
Finally, the website also provides a message area to display messages related to JSON operations. For example, if there is an error while parsing JSON, an error message will be shown in the message area. The style of the message area will be set according to the type of message to clearly distinguish between success and error messages.
In summary, this website is a user-friendly JSON formatting/validation tool that can help you format, validate, and clear JSON data, providing corresponding results and messages. This tool can be used by both developers and users to handle JSON data and ensure its validity.
