By default, all software supports multiple file extensions. QuickBooks supports at least 39 different file extensions. The basic files that QuickBooks supports are .CSV. However, not all of the extensions listed on the list are always used to save the effects of work in QuickBooks. Very often, files with such extensions are used as source data files used by QuickBooks.
QuickBooks can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via QuickBooks and try to save it in another file format, also supported by QuickBooks.
