First ensure your numbers are in ascending order. Use the formula =IF(OR(A2=A1+1,A2=1),'',A2-1) to identify gaps in a single column of sequential numbers.
If you have Excel 365, use the formula =IF(OR(A2=A1+1,A2=1),'',SEQUENCE(1,A2-A1-1,A1+1)) to identify multiple missing items in the sequence.
Use the formula =IFERROR(INDEX(A:A,MATCH(0,COUNTIF(A:A,ROW(A:A)-ROW(A$1)+1),0)),'') to find missing numbers in a sorted sequence. This formula works by counting the occurrences of each number in the sequence.
While Excel offers several methods to find missing sequence numbers, these techniques can be complex and time-consuming.
