=XLOOKUP(Aranan_Değer; Arama_Dizisi; Döndürülecek_Dizi; [Not found]; [Eşleşme_Modu])
Example Scenario: Find the price according to the product code, if not, write "Out of Stock".
=XLOOKUP(A2; D:D; E:E; "Stokta Yok")
It is used to perform logical tests. Instead of using nested IFs for multiple conditions, you can write them more cleanly with IFS (IFS).
=IFS(A2>90; "A"; A2>80; "B"; A2>70; "C"; TRUE; "F")
This function, which comes with the dynamic arrays feature, filters the data according to certain criteria and dynamically pours it into another field.
=FILTER(A2:C100; B2:B100="İstanbul"; "Veri Yok")
Combines text from multiple cells by placing a separator of your choice between them. It can ignore empty cells.
=TEXTJOIN(", "; TRUE; A2:A10)
