Frequently Asked Questions

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data format used for storing and exchanging data. It's easy for humans to read and write, and easy for machines to parse and generate.

Is my data secure?

Yes! All JSON processing happens directly in your browser. Your data is never sent to our servers, ensuring complete privacy and security.

What's the maximum file size?

Since processing happens in your browser, there's no hard limit. However, very large files (>10MB) may slow down your browser.
