Formula conversion from Google Sheets to Microsoft Excel - excel

Question

I am using 2 formulas for finding only duplicate values and listing them in another sheet. But when I downloaded the Spreadsheet as Microsoft Excel (xlsx), QUERY formula and Array function dont work on Microsoft Excel.
So I need your help about Microsoft Excel.
This is my formulas using on Google Sheets. How can I do that on Microsoft Excel? I am open to another formulas or solutions.
=INDEX( QUERY( QUERY( {'DATA'!A2:A}, "SELECT Col1, COUNT(Col1) GROUP BY Col1 ORDER BY Count(Col1) DESC"), "WHERE Col2 > 1",0) ,,1)
Test sheet:

Answer 1

With your shared example:
=UNIQUE(FILTER(DATA!A:A,COUNTIF(DATA!A:A,DATA!A:A)>1))
But this will be real slow, because it calculates each row of column A, also the empty ones.
To workaround we can use:
=LET(data,FILTER(DATA!A:A,DATA!A:A<>""),
u, UNIQUE(data),
FILTER(u, MMULT(--(TRANSPOSE(data)=u),SEQUENCE(ROWS(data),,1,0))>1))
In this case we can't use COUNTIF, because this requires a range, but using LET converts it to array. Therefore MMULT can be used.

Answer 2

Assuming data has a header, you can also use frequency:
=LET(data,DROP(TOCOL(Data!A:A,1),1),
u,UNIQUE(data),
f,DROP(FREQUENCY(data,u),-1),
HSTACK(FILTER(u,f>1),FILTER(f,f>1)))
If hstack is not available, you can try:
=LET(data,DROP(TOCOL(Data!A:A,1),1),
u,UNIQUE(data),
f,DROP(FREQUENCY(data,u),-1),
CHOOSE({1,2},FILTER(u,f>1),FILTER(f,f>1)))
