Frequently Asked Questions

OPML is an XML-based format designed for outlining and exchanging hierarchical information. Created in 2000, it's widely used by outliner applications, RSS readers, and mind-mapping tools to save and share structured content with nested hierarchies.

Popular tools include Workflowy, OmniOutliner, MindNode, Dynalist, Notion (via export), Roam Research, Obsidian outliner plugins, RSS feed readers (Feedly, Inoreader), and most mind-mapping software like MindManager and XMind.

Markdown is universally supported across documentation platforms (GitHub, GitLab, static site generators, note-taking apps) and is human-readable. Converting OPML outlines to Markdown makes them compatible with wikis, blogs, technical documentation, and version control systems.

OPML outline levels become Markdown headings (# ## ###) or nested lists (- * +) depending on the conversion settings. Child nodes become sub-items, preserving your outline's logical structure while making it editable as plain text.

Standard OPML attributes like text, type, and created dates are preserved when possible. The 'text' attribute becomes the heading or list item content. Additional metadata may be included as Markdown front matter or inline annotations depending on Pandoc's conversion rules.

Yes. Workflowy's OPML export contains your entire outline hierarchy. The converter transforms it into nested Markdown lists or headings, making it easy to import into documentation systems, wikis, or other note-taking apps that support Markdown.

Absolutely. All conversion happens locally in your browser using WebAssembly. Your OPML files and their content never leave your device, are not uploaded to any server, and remain completely private on your machine.

OPML is XML-based with rich metadata support but requires specialized software. Markdown is plain text, human-readable, and universally supported. Markdown outlines are version-control friendly and work across thousands of tools without special parsers.

Yes. RSS reader OPML exports (containing feed subscriptions organized by folders) convert to Markdown lists showing your feed hierarchy. This creates a readable backup or documentation of your RSS subscriptions.

After converting OmniOutliner OPML to Markdown, you can edit the outline in any text editor, commit it to Git for version tracking, publish it to static site generators (Jekyll, Hugo, Eleventy), or import it into Markdown-based note apps like Obsidian or Logseq.
