Which steps are necessary to export an Excel worksheet to a CSV file?

To export an Excel worksheet to a CSV file, the steps involve utilizing the File tab to access the Save As feature. This method is specifically designed for saving files in different formats. When you choose to Save As, you can then select CSV from the list of file types. The CSV format is a plain text format that allows for the easy transfer of data, making it a common choice when sharing data with applications that support this format.

The steps in Option A accurately describe this process. Selecting the File tab is the first step, and it leads you to various options, including Save As. From there, choosing CSV ensures that your worksheet is saved in the right format for compatibility with different data processing systems.

Other options do not provide a valid method for exporting to a CSV file. For instance, the Home tab doesn’t contain a direct option for exporting files to CSV. Similarly, the View tab focuses on the display of the worksheet rather than file management, and the Data tab's Export option is meant for exporting to formats like PDF, which is not related to CSV files.
