Why OneNote paste looks broken

OneNote copies a full HTML document with Calibri font tags, table wrappers, highlight colours and hundreds of mso- styles. Most apps either keep all of it or reject it. Paste Cleaner keeps the structure that matters — headings, bold, lists, links, tables — and throws away the rest.

Does my content get uploaded?

No. The cleaning runs entirely in your browser; there is no server and nothing is stored.

What is kept and what is removed?

Kept: headings, paragraphs, bold/italic, lists, links, tables, line breaks. Removed: fonts, colours, highlights, sizes, Office classes, empty spans, images.

Does it work with Word, Outlook and Google Docs?

Yes — they produce the same kind of markup. Use the dedicated pages for tips specific to each app.

Which mode should I pick?

Rich for email, Notion or Word. Plain for text boxes that strip everything anyway. Markdown for Slack, GitHub, Obsidian or Jira.
