Worksheet View

• An Excel worksheet has a grid of columns (labeled with letters) and rows (labeled with numbers). The first 26 columns are labeled A to Z.. Thereafter, the letters are duplicated: AA, AB and so on.
  
  

Cells

• The small boxes on the worksheet are called "cells." The user places data into these cells. Every cell has its own reference, based on its position in the columns and rows.
  
  

Calculations

• Cells can hold numbers, formulas and text. Use formulas to perform calculations on ranges of cells. For example, if you want to add the contents of cells A1 through A10 together, type the formula "=sum(A1:A10)." Place this in another cell of your choice (A11, for instance) to perform the calculation.
