The company behind SumOffice.

Health Informatic Security System, S.L. (HISS) is a software company in Málaga, Spain. We make two products: SumOffice — SumDoc and SumSheet, an office engine that opens Word and Excel files in a fraction of a second, runs their macros and Power Query without Excel and ships with an agent inside the editor — and Layers, a team workspace where a recorded meeting turns into a transcript, a summary page and tasks. Designed and developed in the European Union.

What we make

0.11 s vs 5–15 s

Opens a file it has never seen in a fraction of a second. Browser office suites take five to fifteen seconds for the same document. The free tools on sumoffice.com print the real time next to every result.

VBA · Power Query without Excel

Your macros and queries keep working. Workbook events, VBA procedures and Power Query refreshes run in our engine on Linux, macOS, Windows, iOS and Android — with no Excel on the machine, and the workbook stays intact.

✦ Agent inside the editor

Agents are already in the editor. The assistant reads what the file is made of — macros, queries, connections — proposes the change, and nothing moves until a person presses Apply.

Made in the European Union. A Spanish company, engineering in Málaga, servers in Frankfurt, Germany. The apps process your files on your own device; the free web tools delete uploads after 24 hours.
