# Convert Markdown and HTML in Duaer

In Duaer, the Markdown node converts between Markdown and HTML. The result is written to the field named in Destination Key.
## Turn HTML into Markdown

1. Search for Markdown and connect it after a node that has HTML.
2. Leave Mode on HTML to Markdown.
3. Set HTML to a field or expression, for example {{ $json.body }}.
4. Set Destination Key to the result field name, for example markdown.
5. Select Execute step. That field appears on the output.

Markdown to HTML takes a Markdown field and still writes through Destination Key. Sticky-note Markdown on the canvas is separate. Refer to [Markdown in a Duaer sticky note](/Duaer-Organizations/sticky-notes.md).
## Questions

### Does the Markdown node in Duaer overwrite the original HTML field?

Not by default. The result goes to Destination Key. The original field stays unless you remove it later with Edit Fields.
