Paste .properties or simple YAML. Comments, blank lines, escaped separators, and line continuations are handled for common Java config files.
Use nested YAML for Spring-style configs, or flat keys when you need a safer one-to-one migration.

No. Reverse conversion focuses on simple maps, which are the safest match for .properties files.
The output quotes values by default so app behavior does not change unexpectedly.
No. Conversion happens in the browser text area.
