='Using Dynamic Named Range'!$B:$B:INDEX('Using Dynamic Named Range'!$D:$D,COUNTA('Using Dynamic Named Range'!$D:$D)) 

Formula Breakdown

  • COUNTA(‘Using Dynamic Named Range’!$D:$D)  —-> Here, the COUNTA function will return the number of rows that contains any text or number.
    • Output: 9
  • INDEX(‘Using Dynamic Named Range’!$D:$D,COUNTA(‘Using Dynamic Named Range’!$D:$D)) —-> turns into
    • INDEX(‘Using Dynamic Named Range’!$D:$D,9) —-> Here, the INDEX function will return the value from within the table.
      • Output: $D$9
  • ‘Using Dynamic Named Range’!$B:$B:INDEX(‘Using Dynamic Named Range’!$D:$D,9) —-> turns into
    • ‘Using Dynamic Named Range’!$B:$B:$D$9 —-> Here, the formula will return a dynamic table array range.
      • Output: $B:$B:$D$9
  • Thirdly, press OK.

  • Now, select the cell where you want the obtained marks in Chemistry. Here, I selected cell G5.
  • Next, in cell G5 write the following formula.
=VLOOKUP(G4,Dynamic_Range,3,FALSE)

Using Dynamic Named Range to Expand VLOOKUP Table Array

Here, in the VLOOKUP function, I selected cell G4 as lookup_valueDynamic_Range as table_array, 3 as col_index_num, and FALSE as range_lookup because I want an exact match here. The function will return the exact match for the lookup_value.

  • Finally, press ENTER.
