Frequently asked questions
Common questions about Utility Tools.
The collection includes Markdown, HTML, JSON, YAML, Base64, and related file or text transformations, depending on the selected tool.
Syntax must be parseable, but format conversion alone does not prove that the data follows an application-specific schema.

Not always. Markdown and HTML support different structures, and rendered output can also depend on styles, fonts, and the destination environment.
