Spreadsheet Visual Analyzer

  In order to ease the analysis of specific data in your spreadsheet, you might give it a special format (for example: highlighting it), using one of the most useful tool that Excel has, "Conditional Formatting", but the only bad thing is that it just supports until 3 conditional levels.
But Spreadsheet Visual Analyzer, is an addin, which you can format all the cells and ranges that you need, using "n" conditional formatting levels.
