我如何从具有指定值的单元格开始计算excel中的单元格？

Question

The question is slightly confusing, so I will do my best to elaborate. I have a series of cells in a row with all of the cells in the row with a value of 0 and one cell having a value of 1. I want to use the COUNT function to count all of the cells to the right of the cell that contains the value of 1, including that cell. I would then use this number of counted cells in another equation. Does anyone have any suggestions on how to do this? I have tried using a lookup function inside of the count function, but it has not worked. This is my closest guess:

=COUNT(Lookup(1,A1:J1):J1)

This results in an error. Do I need to use VBA to make this work or should I be able to write an equation? I appreciate the help, or if there are any other strategies that I can use to attain the result I am looking for.

Edit: I am adding in some sample data and expected results. I am trying to count all of the cells to the right of the "1" including the cell containing the "1". So in this example, I would expect the formula to return "13" as there are 12 cells to the right of the "1"

Answer 1

You can use OFFSET() and MATCH():

That last "50" is a bit of a guess since I'm not sure how far to the right you want to count...

...and re-reading your question it's not clear if you only want to count values of 1 or if you also need to count other values as long as they're to the right of the first 1.

Answer 2

With data in A1 through J1 , consider:

=10-MATCH(1,A1:J1,0)+1

In this case. 4 is the number of cells from G1 through J1 , inclusive.

Answer 3

You can use this formula:

=COUNTA(INDEX($A$1:$J$1,1,MATCH(1,$A$1:$J$1,0)):INDEX($A$1:$J$1,1,10))

The benefit to use this is it is not a volatile function, and it will also work for 1 appears in the last column.

Answer 4

Assuming your range of 0 and 1 values is in row 2, starting from column B, use this formula in B3 and copy it across for as far as you need:

=IFERROR(COUNT($B2:B2)+1-MATCH(1,$B2:B2,0),0)

---

You could also use a formula of

=IF(A3>0,1+A3,IF(B2=1,1,0))

but that could cause issues if you have something in cell A3 itself.

Answer 5

You can use "COUNTIF" formula to count number of occurrences of specific number in a range of cells.

To count no of occurrences in a row.

=COUNTIF(1:1,1)

If it is in a column then

=COUNTIF(A:A,1)

Answer 6

Hope you are looking for a countif function.

COUNTIF(A1:A10, 1)

The above function counts the cell that has value 1 within the range A1:A10
