Free online RST to OPML converter

RST is a reStructuredText document format used for technical documentation, especially in Python and Sphinx workflows. OPML is an Outline Processor Markup Language format used to store hierarchical outlines, often for notes, RSS subscriptions, and structured lists.

How rst and opml differ

RST is designed for rich plain-text documentation with headings, lists, links, code blocks, and directives. OPML is XML-based and focuses on nested outline structure rather than full document formatting. Because of this, converting from RST to OPML usually means mapping headings and lists into outline nodes.

When to convert rst to opml

You may want this conversion when you need to turn documentation into a structured outline for planning, note-taking, content organization, or import into outline-based tools. It is especially useful if your RST file mainly contains headings and bullet lists.

Best software for rst to opml conversion

The best option is usually a custom conversion workflow using Python, because direct one-click converters are rare. A practical approach is to parse the RST structure and generate OPML from it. If you already work with documentation tools, Docutils can help read RST, and a small script can export the outline to OPML.

If you need a ready-made desktop or online tool, look for an RST to XML or RST to outline converter, then transform the result into OPML. However, for accuracy and control, a scripted conversion is usually better.

How to convert rst to opml

1. Open the RST file in a parser or editor that supports reStructuredText.
2. Extract the document structure, especially headings and nested lists.
3. Map each heading to an OPML <outline> element.
4. Preserve hierarchy by nesting child outlines under parent nodes.
5. Save the result as an .opml file with valid XML syntax.

If using a script, the workflow may look like File → Open in your editor, then Run → Export or Save As to create the OPML output.

Conversion tips

• Keep the structure simple if the source file contains many formatting elements that do not translate well to outlines.
• Use headings as outline levels for the cleanest result.
• Check XML validity after export to ensure the OPML file opens correctly in outline apps.
• Review special characters such as ampersands and angle brackets so they are properly escaped.

Recommended workflow

For most users, the most reliable method is Python + Docutils + OPML generation. This gives you control over how headings, lists, and links are represented. If you only need a quick conversion and the document is simple, an online converter may be enough, but it may not preserve complex nesting accurately.

Summary

RST is a documentation-oriented plain-text format, while OPML is a hierarchical outline format. The conversion works best when the RST file is treated as a structure to be transformed into nested outline nodes. For the best results, use a Python-based converter or a workflow built around Docutils.
