What is Excel?

Excel is a popular Electronic Spreadsheet Program which allows anyone to enter numerical values or data into the rows or columns of a spreadsheet for calculating, storing, organizing and manipulating data. Excel is always the first choice for statistical analysis.

Excel screen looks like rectangular table or grid of rows and columns. All the horizontal rows are identified by numbers (like 1,2,3) and the vertical columns with letters of the alphabet (like A,B,C). If the columns are more than 26, then those columns are identified by two or more letters such as AA, AB, AC...

All data or values are inserted into cells and the cells are the intersection point between a column and a row. Actually, a cell is the basic unit for storing data in the spreadsheet. As Excel spreadsheet contains thousands of cells, reference is used to identify each cell.
