About us - Ablebits.com

AbleBits.com is a joint project by 4Bits and Add-in Express

4Bits Ltd. is a software development company located in Belarus, Eastern Europe. Established in 2002, the company has grown steadily over the years to become a respected manufacture of software for Microsoft Excel, Outlook, Word as well as add-ins for Office for Mac.

Starting from 2013, we've been developing add-ons for Google Sheets and Google Docs as well. The tools turned out to be extremely useful and the number of users has been growing since. In 2020, a small team standing behind the add-ons spun off into a separate company – APPS4GS Ltd. Their focus hasn't changed since and Ablebits remains their trademark.

Add-in Express is a privately held software development company also located in Belarus. Established in 1998, the company's primary focus has been on creating development frameworks for Microsoft Office integration and extending Office applications with custom functionality. All solutions published on this web-site are built on the unique technology of Add-in Express.

AbleBits.com software products are designed and developed by true professionals with a long-term experience in the Microsoft Office extensibility industry. Over the years we've been adding new features, refining the code and polishing up the interfaces to make the solutions as perfect as they can possibly be.

We hope that our time-saving tools will become your reliable assistants and help you accomplish your day-to-day tasks quickly and efficiently.
