ASAP Utilities does not work with the spreadsheet program Calc (included with OpenOffice or LibreOffice).

ASAP Utilities is written in VBA, the programming language for MS Excel. OpenOffice/Libre Office has limited VBA compatibility, but it is not sufficient for complex add-ins like ASAP Utilities. At this moment Calc differs to much from Excel to create a ASAP Utilities for Calc. We would have to rewrite the entire program, and that takes way too much time (too learn Calc, learn the new programming language, and to rewrite all the tools).
