How .properties to YAML conversion works

Dot-separated keys like db.pool.size=10 are automatically converted to nested YAML structures. Comments (# or !) are stripped. Scalar values that could be misread as YAML booleans or numbers are quoted automatically.

For the reverse direction, try YAML to JSON. To go from Properties to JSON instead, use Properties to JSON.
