What is a spreadsheet?

A spreadsheet is a program that allows the user to enter data into matrix of cells. Each cell can be individually addressed based on its row and column number. In Mesa, rows are numbered from 1 to 16384 and columns are labeled from A to XFD. Each cell has a value and formatting information. The cell's value is based on either its contents (e.g., a number like 5, or a string like Hello) or on a formula that is evaluated to result in the cell's value. A value can be a number (e.g., 1, 4.7, 5280), a string (e.g., Hello, June Stock Prices, Eastern Region), or an error (e.g., !ERR, !/0).

A formula can refer to the value in a cell during calculation. This is why spreadsheets are so powerful. Because the value in one cell can depend on the value in another cell, when the first cell is changed, the second cell updates itself properly. For example, if a cell contained the formula =A1+1, when the value in cell A1 is changed, the cell containing the formula automatically updates itself.

Cells also contain formatting information. This includes the text format of the display (e.g., General number, Scientific notation, Currency format), the color of the text, the background color of the cell, and more. Information can be presented in a more visually pleasing or informative manner by changing the cell formatting. Mesa allows some of the cell's formatting to be changed by the cell's formula so that a cell can automatically change its color if it contains certain values. This feature allows worksheets to alert the user to important cells that contain critical values.

Once the cells have been populated with values, and the spreadsheet has been formatted, it can be printed out, e-mailed to others, or saved. In addition, Mesa allows you to graph the values in cells to produce presentation-quality graphs and include those graphs in reports or copy the graphs or groups of cells and paste them into other MAC OS X applications. Mesa can also import data from Excel and some other common delimited text files.

Once the data has been entered into Mesa from various different sources, the formulas have been entered so that the raw data can be summarized, the formatting has been applied, and the charts and graphs have been created, you can print the worksheet in order to produce a presentation quality report.
