By default, Yellowfin assumes that the first row of your CSV contains the text to be used as column titles, rather than data itself. To change this option you can uncheck the First row contains unique titles option at the bottom-left of the page. This will take the first row of the CSV and treat it as data, allowing you to provide your own labels. If you wish to change some or all of the column titles displayed, you can click on the title, which will select it and allow you to enter new text
