Frequently Asked Questions






What is JSON?


JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write and easy for machines to parse and generate. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.






Why would I need to format JSON?


Formatting JSON makes it easier to read and understand, especially for large or complex datasets. It adds indentation and line breaks, which helps in identifying the structure of the data, such as nested objects and arrays. This is particularly useful for debugging, code reviews, or sharing JSON data with others.






Is my data secure when using this tool?


Yes, all processing happens locally in your browser. None of your JSON data is sent to any server or stored anywhere. You can use this tool confidently with sensitive data.






Can I use this tool offline?
