Frequently Asked Questions (FAQ)

What is a JSON formatter and why do I need one?
A JSON formatter prettifies minified or messy JSON code by adding indentation, line breaks, and structure. It's essential for debugging APIs, reading config files, or sharing data—making complex objects human-readable without errors.
Is json2apex really free and secure?
Yes! Our tool is 100% free with no sign-ups or limits. All processing happens in your browser, so your data never leaves your device—perfect for sensitive API responses or private projects.
How does the JSON to Apex converter work?
Our converter parses your JSON input, generates structured Apex classes with appropriate data types, and creates corresponding test classes to ensure Salesforce compatibility. It supports nested objects and arrays, with optional parse methods.
Can I use this for large JSON files?
Absolutely. Handle files up to several MB with our efficient parser. For massive datasets, ensure your JSON is valid to avoid performance issues.
What makes json2apex better than other tools?
Unlike basic converters, we generate both Apex classes and test classes, support complex JSON structures, and offer features like file uploads and dark mode in a user-friendly, ad-free interface.
