DOCX to Markdown: Format Guide for Document System Migration

DOCX is stored based on the OOXML specification, and describes formats with styles as the core. The same semantic content can be presented in multiple visual styles. Markdown takes semantics as the core, uses concise syntax to mark content hierarchy, and adapts to rendering of various static document systems.

The core requirement of technical document migration is to convert the visual styles in DOCX into semantic markers recognizable by Markdown, remove redundant page layout information, and retain the hierarchical relationship of content.

The mapping rules follow the semantics-first principle, only retain content markers that conform to Markdown specifications, and discard layout information such as page margins and line spacing in Word. Conversion tools match the corresponding heading level based on Word's built-in style levels, and custom styles need to rely on the tool's style recognition rules.

Pure format conversion tools only extract images embedded in Word documents, generate corresponding Markdown image link syntax, and do not automatically complete cloud storage upload of images. Extracted images retain the original file resolution and format, and no compression or format transcoding is performed.

When migrating documents, users need to upload the extracted images to the image hosting of the document system themselves, and replace the generated local path to enable normal display of images.

Current mainstream browser-side DOCX to Markdown tools are developed based on mammoth.js. This library only supports DOCX files conforming to the OOXML specification, and does not support legacy binary-format DOC files.

Legacy DOC files need to be exported to DOCX format via Word or LibreOffice first, then processed with a DOCX to Markdown converter to get conversion results that conform to the rules.

After completing DOCX to Markdown conversion and content revision, you can combine different tools to complete delivery according to the publishing target. For GitBook or VitePress, you can directly store the converted Markdown in the content directory of the corresponding project, and cooperate with build tools to generate a static site.

For online document systems such as Yuque, you can directly import the converted Markdown file, and the system will automatically complete syntax rendering and retain the original content hierarchy. When you need to export to PDF or a new Word document, you can use Pandoc to complete the format conversion, and the parameters are subject to the current official announcement.
