Final answer:
Freezing the top two rows of a spreadsheet is done to keep headers visible during scrolling, to edit data only in those rows without losing sight of them, to keep important data in view when scrolling through a large dataset, and potentially to protect data by keeping it constantly in view.
Step-by-step explanation:
Freezing the top two rows of a spreadsheet is a common practice that is used for several purposes. One of the main reasons is to keep headers visible as you scroll down through the data. Headers typically contain important information such as column names that help users understand what the data in each column represents. By freezing the top rows, these headers stay at the top of the spreadsheet, making data analysis and navigation easier.
Another reason for freezing rows is when you want to edit data exclusively in those top rows while still being able to view the rest of the sheet. This can be particularly useful if you need to make constant adjustments or updates to key figures that are referenced throughout the spreadsheet. Keeping these essential rows in view at all times helps maintain accuracy during the editing process.
Moreover, it is often beneficial to see certain data at the top of a spreadsheet when working with large quantities of information. For instance, if the first two rows contain summary or total figures, it might be necessary to compare these totals with individual data entries found further down the spreadsheet.
Last but not least, freezing the top rows can help to protect data. While it does not prevent others from making changes, it does ensure that the frozen rows remain on screen and any accidental or deliberate attempts to alter data can be more easily noticed. It's a method of keeping critical information in sight, which can be a deterrent against unwanted modifications.
