Hi!

Assume your entries are in the range B1:W1

In B2 enter this formula:

=IF(C1<B1,1,"")

In C2 enter this formula and copy across to W2:

=IF(D1<C1,COLUMNS($B1:C1)-IF(COUNT($B2:B2),LOOKUP(2,1/ISNUMBER($B2:B2),COLUMN($B1:B1)-1),0),"")

To count the number of times 1 is entered in 3 consecutive cells:

=SUMPRODUCT(--(B1:W1=1),--(B2:W2=3))

for example if you have values of

1 0 1 1 1 0 0 0 1 1 1 0 0 0 1 1 0 0 0 1 1 1
how to count number of occurances where value of 1 is 3 consecutive
times? Obviously answer is 3 in this instance but is there an excel
formula to count/sum this?

Thanks in advance :)
