If you would like to find out how many occurrences of the same number occur in a column in Excel, keep reading.
Example
1111155555555666666666666 (vertical column, although not depicted here)
1's=50
5's=8
6's=12
We have merged multiple columns into a single column totalling 5000 and we have sorted them numerically, but there are just too many to manually count.
So, if the numbers are different cells in a column and if the total no. of rows is 5000. We can use this formula:
=countif(a1:a5000,"1")
In case of a whole string or number in one cell we should use this (supposing the cell is E1):
=LEN(E1)-LEN(SUBSTITUTE(E1,"1",""))
