Check for empty excel file

@sarathi125

My file don’t have header, so if there is atleast one row with information it would be always count in rowCount = 0.

This is the point that sometimes I can have ONLY one row, and the counter would be always 0.

I was thinking something about to count the first cell A1 is it empty string.
If A1 is empty for sure the file don’t contain information and he is empty.

But now I must understand how to check for empty string in specific cell.
