What option should you deselect if your CSV file's first row does not contain column names?

Deselecting the option that indicates "first row contains field names" is the correct action when your CSV file's first row does not contain actual column names. This selection is typically a checkbox that tells the data input tool to treat the first row as header information. When this option is deselected, the tool understands that it should read all the data in the rows, including the first row, as regular data entries rather than as headers. As a result, your dataset will correctly include all information from your CSV file without misinterpreting the first row.

Selecting the option to indicate that the first row contains field names when it does not would lead to errors, as the input tool would skip the data of the first row, assuming it includes headers. Keeping all default settings might include that first-row selection, leading to similar data interpretation issues. Using the dynamic input tool would not address the specific context of handling the CSV file's structure regarding headers either.
