There are a few things to consider when choosing direction after entering on a workbook basis in Excel. First, think about the type of data you are working with. If you are working with numerical data, you may want to choose a left-to-right direction. However, if you are working with text data, you may want to choose a right-to-left direction. Second, consider the structure of your data. If your data is organized in columns, you may want to choose a left-to-right direction. However, if your data is organized in rows, you may want to choose a top-to-bottom direction.

Third, think about how you want to enter your data. If you want to enter your data manually, you may want to choose a left-to-right or top-to-bottom direction. However, if you want to import your data from another source, you may want to choose a right-to-left direction. Fourth, consider the format of your data. If your data is in a tabular format, you may want to choose a left-to-right or top-to-bottom direction. However, if your data is in a non-tabular format, you may want to choose a right-to-left direction.

Finally, think about the size of your data. If you are working with a large amount of data, you may want to choose a left-to-right or top-to-bottom direction. However, if you are working with a small amount of data, you may want to choose a right-to-left direction.
