dot.case (also called dot notation) is a naming convention where words are written in all lowercase and separated by periods, for example "user.first.name" or "app.config.debug".

Does it handle camelCase input?

Yes. The converter detects camelCase and PascalCase boundaries and splits them into separate words before joining with dots, so "myVariableName" becomes "my.variable.name".

What about numbers and special characters?

Numbers are kept as-is and treated as word boundaries when adjacent to letters (e.g. "step1Title" becomes "step.1.title"). Most punctuation other than underscores, hyphens, and dots is stripped.

Can I convert multiple lines at once?

Yes. Each non-empty line is converted independently and the results are stacked line by line in the output.

Is the conversion reversible?

dot.case only stores lowercase words separated by dots, so original casing from camelCase or PascalCase is lost. The conversion is not automatically reversible.
