# Count number a times a specific value appears consecutively.

1. ## Count number a times a specific value appears consecutively.

Would like a function formula that counts the number a times a specific value appears consecutively in a specific column.

Ex. In column H62:H96, the values appear (vertically):
1, 1, 0, 1, 0, 1, 0, 0, 1, 1, 1, 1, 1, 1, 1, 0, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0

I would like a formula i could drag across multiple columns that calculates the number of times the value '1' appears consecutively. However, i dont want it to count every time it appears consecutively, only the time it appears the most. For example, the above sequence would yield a value of 7 because the number 1 appeared 7 times in a row at its max.

Thank you!

Try this array formula**:

=MAX(FREQUENCY(IF(H62:H96=1,ROW(H62:H96)),IF(H62:H96<>1,ROW(H62:H96))))

** array formulas need to be entered using the key
combination of CTRL,SHIFT,ENTER (not just ENTER).
Hold down both the CTRL key and the SHIFT key
then hit ENTER.
