Excel Add-ins

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. In that post, I listed individual products, but the number of different products is too large now to keep up-to-date, so this page lists the company and/or the company's primary product. Learn About Add-ins at support.office.com.
