How do you write the formula to check for duplicates from an entire range A2:J5?

How would I write the formula in cell L2 to check for duplicates for the entire range A2:J5? Just in case there are duplicates of x,y coordinates on another row? For example if cell I5 is -2 and cell J5 is -7, this will be an x,y coordinates of -2,-7 in row four and not just in row one. The formula in L5 =LET(f,FILTER(A5:J5,A5:J5<>""),s,SEQUENCE(COLUMNS(f)/2,,0),u,UNIQUE(INDEX(f,,s*2+{1,2})),ss,SEQUENCE(COUNT(u),,0),TRANSPOSE(INDEX(u,INT(ss/2)+1,MOD(ss,2)+1))) of row four will not recognize -2,-7 as a duplicate from row one so -2,-7 and will be displayed twice, in range L2:U5 in row one and in row four.

Does the VLOOKUP table have to be sorted?
No! when you are using an exact match, the VLOOKUP table can be in any order. Best-selling items at the top is actually the best.

Hopefully this all works in excel 2021

My results was #NAME?. So how do I remove that error?

Some of those functions are not available in Excel 2021 so if you have it there is a need for alternative approach...

This is incomprehensible in 2021, but this should work. I had to mangle some arrays.

You need to change the choosecols to Index for 2021.

That was the short version range A2:J5. My actual range is ADU140:AJN159. It has the same x,y data format but with 150 columns and 20 rows. Anyway, what do I need to revise on your formula besides just changing range A2:J5 to range ADU140:AJN159. I figured it would work just be changing the range. Right now, I just get a 0 in cell ADU140.
