Excel functions that don't exist in Google Sheets

PIVOTBY, GROUPBY, the CUBE family, AGGREGATE and more are documented for Excel but absent from Google Sheets — importing an .xlsx that uses them leaves broken formulas.

53 functions, from each vendor’s official documentation — with LibreOffice’s status from our executed tests where available. Formulas using these break with #NAME? when a file moves to the other app.

The LibreOffice column shows that "Excel-only" is often really "not-in-Sheets": several of these run fine in LibreOffice Calc per our executed tests.

See the Excel ↔ Google Sheets equivalents table for the documented replacement to use for each. Part of the Excel vs Google Sheets formula compatibility guide.
