Extract Emails from Excel Online
Extract emails from excel: find mailto hyperlinks and address patterns in cells, append an Email column, preview and download xlsx.
Sources of emails
mailto: hyperlinks, addresses typed as plain text, and mixed cells that contain both a name and an email.
Paired with hyperlinks
The same run also fills a Hyperlink column for websites—useful when a CRM row has both a site and a contact email.
Deduping within a row
Duplicate addresses in the same row are collapsed; multiple distinct emails are joined with semicolons.

FAQ
Does it validate MX records?
No. It extracts address-shaped text and mailto targets; deliverability is not checked.
International domains?
Common email patterns are matched; review unusual TLD edge cases after export.
Separate email-only export?
Use the tool, then keep only the Email column with Extract Columns if needed.
