How do you open data contained within one cell of a variable?

I have imported a number of excel files, Trial 7 to Trial 54. They have all imported into one variable and within that variable you have to double click a cell to see all the data for that Trial.

I am now trying to process the data to work out the time to do this I need to count the number of zeros however when writing the code I can access a row and column within the variable however this doesn't open the data within that cell. Is there code which accesses the data within a cell?

your cell array A should be a 1x54 cell, to access your data use a curly brackets

A{1}
A{2}
