CSV, or comma separated value, is a very simple file format that stores an Excel spreadsheet-like table of information inside a file, with each value separated by a single comma. A QBO, or QuickBOoks file, is the file format used by QuickBooks Financial software. Converting to QBO is necessary to share financial information between multiple users of Intuit Quickbooks.
