Fill ArrayFormula with dynamic IMPORTRANGE

Question

I have a Google Sheets that collects marks of students from various sheets to create a complete mark sheet. Each teacher enters marks in his/her own spreadsheet with paper numbe

Answer 1

As the importrange function has the ability to output arrays, it can't be iterated across an array.

To combine your formula, use this formula:

="=sort(ARRAYFORMULA({"&JOIN(";",ArrayFormula("IMPORTRANGE("""&VLOOKUP(FILTER(G2:G20,G2:G20<>""),Sheet3!$A$2:$B,2,0)&""","""&G1&"!A2:B"")"))&"}),1,True,2,True)"

then you could paste the result in G23 manually or use script to paste formula
