How it works

When you copy from OneNote, Word, Outlook or Google Docs, the clipboard carries two versions of your content: plain text and an HTML document full of application-specific styling. Most destinations either paste the messy HTML or throw everything away.

What happens on paste

1. The HTML flavour is read from the clipboard and sanitised with DOMPurify.
2. Inline bold, italic and underline styles are converted into real tags; Word-style fake lists become real lists; single-cell wrapper tables are unwrapped.
3. Every style, class, font and colour attribute is removed. Links are kept only if they point to http, https or mailto.
4. The result is rendered as a preview and converted to plain text and Markdown.

What "Copy" writes

Rich writes both HTML and plain text to the clipboard, so rich editors keep structure and plain fields get text. Plain writes text only. Markdown writes Markdown as text.
