Frequently asked questions
Does it handle complex tables with merged cells?+
Standard GFM tables convert perfectly. Merged cells (rowspan/colspan) require HTML directly — Markdown doesn't support them natively.
Will Mermaid diagrams render?+
Mermaid code fences are preserved as <pre><code> blocks. To render them, include the Mermaid.js script in your destination page.
Is this suitable for Confluence import?+
Yes, but use the Markdown to Jira tool if you want native Confluence wiki markup instead of HTML.
