Why did some formatting disappear?

Markdown cannot express everything HTML can. Inline styles, spans, tables with merged cells and layout markup have no equivalent, so they are dropped rather than approximated.

Can I go the other way?

Yes — the Markdown to HTML tool converts back, and the Markdown Preview tool shows the rendered result live.

About this tool

Converts HTML into Markdown, keeping headings, lists, links, emphasis and code blocks. Useful for moving content out of a CMS, turning a rendered page into something editable, or cleaning up pasted rich text.

Limitations

Markdown cannot express every HTML structure. Complex tables and inline styles degrade to raw HTML or are dropped.
