Frequently Asked Questions
What does the Markdown Formatter normalize?
It can normalize heading spacing, list markers, blank lines, blockquotes, table alignment, emphasis, links, and fenced code blocks.
Are code blocks changed?
Their boundaries and indentation may be normalized, but the code inside should remain unchanged unless a separate code formatter is explicitly enabled.
Can different Markdown flavors behave differently?
Yes. CommonMark, GitHub Flavored Markdown, and platform-specific extensions may interpret some syntax differently, so advanced documents should be reviewed after formatting.
Is my Markdown uploaded?
No. Markdown formatting runs locally in your browser.
