OPML File Format

Outline Processor Markup category

OPML is the outline-exchange XML: nested <outline> elements that carry subscription lists (podcast apps, RSS readers) and mind-map exports from Workflowy, Dynalist and OmniOutliner.

Typical use: Convert OPML outlines into Markdown or Word documents, or turn bullet lists back into an importable outline.

About the OPML format

OPML (Outline Processor Markup) is XML for hierarchies: nested <outline> elements, each with text and optional attributes. It is the silent standard behind podcast and RSS subscription lists — every "export subscriptions" button produces one — and the interchange format for outliners like Workflowy, Dynalist and OmniOutliner.

An outline is already half a document: Pandoc turns OPML hierarchies into Markdown headings, Word outlines or HTML pages with the nesting preserved, and can write OPML back out so a bulleted plan becomes an importable tree in your outliner of choice.

Strengths

✗ Attribute conventions vary between apps
✗ Rarely rendered directly for humans

Structure: XML <outline> tree
