Microsoft Excel is a software application or program designed and developed by Microsoft Inc., for analyzing and visualizing spreadsheet documents.

A spreadsheet can be defined as a file or document which comprises of cells in a tabulated format (rows and columns) typically used for formatting, arranging, analyzing, storing, calculating and sorting data on computer systems.

A contextual tab is a special tab that are usually hidden and would only appear when a particular object such as a shape, audio or chart is selected. It contains manipulating, editing and formatting commands that are specific to the object an end user is currently working on.

For example, a new Format tab would appear after adding an audio to a spreadsheet document.

Hence, the function of the audio tools on the Format contextual tab is to determine how an audio file will appear on a slide.
