CSV files are columns of values separated by commas. They can be opened as a spreadsheet or in a text file. When looking at the CSV file as a spreadsheet, the commas are represented by the column dividers. CSV files can either contain headers or not. Headers are the descriptive names of the individual columns. They are always the first row of data if they are in the file. An example of a file with headers is shown below:
An example of a file without headers is shown below:
If your file does not contain headers, leave the box shown below unchecked.
