Frequently Asked Questions
Common questions about JSON formatting
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 data exchange between web applications and APIs.
Why do I need to format JSON?
Formatted JSON is easier to read and debug. Proper indentation and line breaks help developers understand the structure of data, making it easier to identify errors and maintain code. It's especially useful when working with large or complex JSON files.
How do I validate if JSON is valid?
When you paste JSON into the tool and click "Format" or "Minify", the tool automatically validates the JSON syntax. If the JSON is invalid, you'll see an error message indicating what's wrong. Valid JSON must have proper brackets, quotes, and commas.
Can minified JSON be restored to formatted version?
Yes! Minified JSON contains all the same data, just without whitespace. You can paste minified JSON into the tool and click "Format" to restore it to a readable, formatted version with proper indentation.
Is my data secure?
Yes, absolutely! All JSON processing happens entirely in your browser. Your data is never sent to any server, uploaded to the cloud, or stored anywhere. Everything is processed locally, ensuring complete privacy and security.
