Frequently Asked Questions

How are nested JSON objects converted?

Nested objects are flattened using dot notation. For example, {"database": {"host": "localhost"}} becomes database.host=localhost.

How are arrays handled in Properties format?

Arrays are converted using indexed keys. For example, ["a", "b", "c"] becomes array.0=a, array.1=b, array.2=c.

Can I convert JSON data directly?

Yes! You can paste JSON directly into the input editor or import JSON data from various sources using the import button.

How are special characters handled?

Special characters like =, :, #, !, newlines, and Unicode characters are automatically escaped according to Properties format standards.

What data types are preserved?

Boolean values (true/false) and numbers are preserved as-is. Null values become empty strings. Strings are escaped as needed.
