Pls tell how I can count the occurence of particular number in list of
numbers separated by comma in single cell.I would further extend this
counting to the entire column.

Eg the number in a first cell : 2,3,4,5
Second cell: 2,3,6
third cell : 3,5,7 . . .
....
Here the answer expected from excel programming is 2.

=SUMPRODUCT(LEN(","&A1:A3&",")-LEN(SUBSTITUTE(","&A1:A3&",",",2,",",,")))
