About HTML to JSX Converter

When migrating HTML templates to React, several attribute names and patterns need to change to conform to JSX syntax. JSX uses camelCase for most HTML attributes and reserves words like class and for (which are JavaScript keywords) — replacing them with className and htmlFor. Void (self-closing) elements must end with />, and inline styles must be JavaScript objects rather than strings. This converter handles all these transformations automatically using regex-based string processing.
