Excel cells can now hold more than one value at a time.
Microsoft announced the change in a Tech Community blog post published September 25, 2026, describing Excel cells that can now store multiple values instead of being limited to one. The post links out to Microsoft's 365 Insider blog, the channel Microsoft uses to preview features before they reach general release. Rather than splitting related information across extra columns, users can now keep more than one piece of data inside a single cell.
The one-value-per-cell rule has held since the earliest spreadsheet programs of the late 1970s and 1980s, and it is the assumption most Excel formulas, pivot tables, and macros are built on. Database-style tools like Airtable and Notion have long let a single field hold multiple tags or linked records, and Excel has been edging toward that model for years with dynamic arrays and structured data types. Letting a cell hold multiple values is a small technical tweak with an outsized implication: the boundary between spreadsheet and database keeps getting blurrier.
Excel has absorbed bigger changes than this without becoming a database. Don't expect VLOOKUP to get replaced anytime soon.
