OPML to DOTX Converter
Processing entirely on your device — large files may take a moment.
Outline Processor Markup and Word Template (OOXML) exist for different jobs: 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. Convert DOTX templates to PDF for review or into filled documents.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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
- ✓Universal outline exchange between outliners
- ✓The RSS/podcast subscription standard
- ✓Trivially parseable XML
! Limitations
- −Hierarchies only — no rich text per node
- −Attribute conventions vary between apps
- −Rarely rendered directly for humans
About the DOTX format
DOCX is the modern Microsoft Word format (Office Open XML, default since Word 2007). A file is actually a ZIP package of XML parts — document body, styles, numbering, headers, embedded media — which is what lets Word, Google Docs, LibreOffice, WPS and Pages all open it natively. Text flows around styles rather than absolute positions, so a document adapts to the page it is rendered on.
It is the format of collaboration: tracked changes, comments, styles and templates are first-class citizens, and office ecosystems assume it. The trade-off is layout drift — the same DOCX paginates slightly differently across renderers, and very complex layouts (exact positioning, text over images) can shift. For contracts in progress it is ideal; for the signed final, export a PDF.
+ Strengths
- ✓Fully editable with styles, track changes and comments
- ✓Opens natively in Word, Google Docs, WPS, LibreOffice
- ✓Flowing layout adapts to any page size
! Limitations
- −Pagination and layout shift between renderers
- −Complex layouts may not survive round-trips
- −Not suitable as a final, fixed distribution format
Why convert OPML to DOTX?
Think of it as moving your file to the container that fits the job. Hierarchies only — no rich text per node DOTX works differently: Fully editable with styles, track changes and comments If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this OPML to DOTX converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for OPML to DOTX?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Can I edit the DOTX result afterwards?
That depends on the target: DOTX is designed for what it does, and this converter reproduces its content faithfully rather than inventing editable structure. For heavy re-editing, work from a format built for editing and export the final version here.
Does the conversion work offline?
Yes. Once the page has loaded, the conversion itself runs entirely inside your browser — you can even disconnect and keep converting. No file ever touches a server.
