Why the Markdown intermediate path is cleaner than direct Word import
Confluence's storage format (XHTML) and Word's OOXML diverge in non-obvious ways. The native importer makes guesses about the mapping, and the guesses fail often enough on real-world documents to require manual cleanup on every import. Markdown, by contrast, is a constrained intermediate: it doesn't carry Word's style baggage, and Confluence's Markdown handling (via "Insert Markup" or paste) is mature.
Convert each Word document on Word to Markdown, copy the Markdown, in Confluence use Insert > Markup > Markdown (or just paste — newer Confluence versions auto-detect). The resulting page mirrors the source document's structure with significantly fewer fixups.
Honest scope note for mass migrations
The web tool converts one document at a time — the right surface for migrating 10-50 important documents progressively. For corporate-scale migrations of thousands of Word documents, the honest enterprise workflows are: (a) Pandoc locally in a shell loop for the .md generation, then Confluence's REST API to upload programmatically, (b) assigning the migration to a small team that converts and uploads documents in a structured queue over weeks, or (c) Atlassian-marketplace migration tools built specifically for the use case. The web tool plus manual paste is the right surface for progressive migration; large-scale migration needs different infrastructure.
