If you process CSV files exported from your online store with Microsoft Excel, you may encounter an issue where Excel causes cell contents to be displayed in a wrong format.
The problem is that Excel automatically attempts to recognize the format of the information contained in the cells (text, date etc.), but the information needed to identify it is not available in the CSV file format.
