For a worksheet with numerical information but no dollar amounts, what formatting is most useful?

Using Comma Style for a worksheet with numerical information but no dollar amounts is advantageous because this formatting helps to enhance the readability of numerical data. Comma Style applies a thousands separator, which makes large numbers easier to interpret at a glance. For instance, instead of seeing a number like "1000000," it gets transformed to "1,000,000," allowing for quicker comprehension of the number's magnitude.

Additionally, Comma Style maintains a uniform appearance across the worksheet while not assigning a specific monetary value to the numbers presented. This is particularly beneficial when working with general numerical data that doesn't represent currency but still requires clear presentation, such as population figures, quantities, or other metrics.

In contrast, using Currency Style would imply that the numbers are associated with monetary values, which isn't applicable in this case. Fraction Style is mainly useful for representing values as fractions, and while this could be suitable in certain contexts, it does not aid general data readability. Percentage Style is designed for values that represent parts of a whole, which may distract from the overall numerical data presentation if the context does not involve percentages.
