Frequently Asked Questions
What is JSON?
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 widely used for transmitting data between a server and a web application.
Is my data safe with this tool?
Yes, 100% safe. This tool operates entirely within your browser. Your JSON data is never sent over the internet or stored on any server, ensuring complete privacy and confidentiality.
What does "beautify" or "format" JSON mean?
It means taking raw, often minified (all on one line) JSON data and adding line breaks and indentation. This makes the hierarchical structure of the data easy to see and understand, which is crucial for debugging and development.
How does the validation work?
The tool attempts to parse your input using JavaScript's built-in JSON parser. If the parser succeeds, your JSON is valid. If it fails (due to a syntax error like a missing comma or quote), it catches the error and displays a message indicating that the JSON is invalid.
