I don't think the article is suggesting stop using spreadsheets - it says some companies are adopting "cloud" based solutions that offer collaboration features and other tools. Not sure if these cloud offerings have the same breadth of features that Excel has as I've never used them, but Workviva seems to be some sort of cloud based spreadsheet and analytics tool.
