> (It is incredible how flexible and effective Excel is for such a wide variety of use-cases) I worked for a Japanese company, and they used Excel for everything . GANTT Charts were done in Excel (not Project), documentation was written in Excel (not Word), etc. They had these monster 3,000-row excel punchlists for QC. If even one test failed, the whole shooting match was scrapped.
Slideshows were done in Excel (not PP).
