Excel is a spreadsheet application developed and published by Microsoft. It is part of the Microsoft Office suite of productivity software.
Unlike a word processor, such as Microsoft Word, Excel organizes data in columns and rows. Rows and columns intersect at a space called a cell. Each cell can contain a single of data, such as text, a numerical value, or a formula.
Excel was originally code-named Odyssey during development. It was first released on September 30, 1985.
