This page lists companies providing Add Ins and related Excel software. It is not a comprehensive list. There are hundreds of providers and authors of Excel Add-ins ranging from individual Excel developers to companies that employ many people to help support and develop their tools.

Learn About Add-ins at support.office.com.
