Frequently Asked Questions

Q: What is JSON?

A: JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page).

Q: What happens if my JSON is invalid?

A: The tool will display an error message indicating the location and type of error in your JSON code. You can then correct the error and re-validate the JSON.
