Final answer:
To quickly apply different formatting to an Excel workbook, the most efficient technique is to use the 'Applying different Cell Styles' function, which provides a set of predefined formats accessible from the Home tab in the Styles group.
Step-by-step explanation:
The formatting technique that can be used to quickly apply different formattings to an Excel workbook is Applying different Cell Styles. Cell Styles in Excel are a set of predefined formats that you can apply to the cells in your worksheets. You can access a variety of styles, including but not limited to, styles for titles, headings, and thematic elements that match the overall design of your workbook.
To apply a Cell Style, simply select the cell or range of cells you want to format, go to the Home tab, and in the Styles group, you can click on 'Cell Styles' to open the gallery of styles. From there, you can choose the desired style by clicking on it, and the formatting will immediately apply to the selected cells.
Using Cell Styles not only gives your workbook a consistent and professional look, but it also saves time, as you do not need to manually set each formatting option, such as font size, font style, borders, and text alignment. It's a feature that's particularly useful when dealing with large or complex data sets where uniformity and readability are important.
