Microsoft Tests Multiple Values per Cell in 21 With New Lists and Arrays

Microsoft is testing a version of Excel that lets a single cell hold more than one value, a break from the spreadsheet's long-standing one-cell, one-value model. The preview adds lists, arrays in cells, and nested arrays, according to a Microsoft 365 Insider blog post by Jake Armstrong, senior product manager for Excel. The feature is opt-in and currently limited to Microsoft 365 Insiders in the Excel Beta Channel on Windows and Mac.
