Properties Converters
Convert Java .properties files to JSON, YAML, INI and TOML.
- Turn .properties files into JSON for modern tooling.
- Migrate Java-style configs without a build step.
- Round-trip with JSON converters on the same hub index.
Properties → JSON
Parse Java .properties files into JSON for Spring configs, i18n bundles and CI validation.
Properties → YAML
Emit YAML from .properties while keeping dotted keys flat — handy for GitOps migration without manual JSON hops.
Properties → INI
Export flat .properties to INI key=value lines — dotted keys stay top-level, not [sections].
Properties → TOML
Move .properties into TOML with flat dotted keys at the root — Sort TOML keys option included.
