You can use the following formula in Google Sheets to count the number of TRUE values in a given column:
=COUNTIF(A2:A11, TRUE)
This particular formula counts the number of cells in A2:A11 that contain the value TRUE in the cell.
The following example shows how to use this syntax in practice.
Example: COUNT IF True in Google Sheets
Suppose we have the following column of TRUE and FALSE values in Google Sheets:
We can use the following formula to count the number of TRUE values in the column:
=COUNTIF(A2:A11, TRUE)
The following screenshot shows how to use this formula in practice:
From the output we can see that there are 6 total TRUE values in the column.
We can manually verify this is correct by counting the TRUE values in the column:
There are indeed 6 total TRUE values.
Note: To count the number of FALSE values in the column instead, simply replace TRUE with FALSE in the formula.
