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.

← Back to tools hub

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.
