Frequently Asked Questions

What is Properties format?

Properties files are simple text files used for configuration in Java applications. They contain key-value pairs separated by '=' or ':'.

How are nested objects handled?

Properties files don't support nested objects natively. Nested structures are typically represented using dot notation (e.g., database.host=localhost).

What data types are supported?

The converter automatically detects numbers, booleans (true/false), and keeps strings as-is. Unicode escapes (\uXXXX) are also supported.

How are comments handled?

Lines starting with '#' or '!' are treated as comments and ignored during conversion. Inline comments are not supported.

Can I use multiline values?

Yes! Use a backslash (\) at the end of a line to continue the value on the next line. This is especially useful for long text values.
