Excel Lets Cells Hold Lists

Microsoft is introducing native single‑cell lists and nested arrays in Excel, plus new functions (HAS/HASANY/HASALL, FLATTEN) and a way to 'wrap' spilled arrays to keep them inside one cell. The change converts ordinary cells into richer data containers and gives spreadsheet users structured, nestable data without leaving the worksheet. — This turns ubiquitous spreadsheets into lightweight databases and programmatic surfaces, shifting where complex logic and corporate data live and who can manipulate it — raising governance, auditing, and automation questions.
