The application allows you to save to MML format, or export to .csv, .tsv, .txt or .exp. You also have the possibility to import other databases from the mentioned file formats as they're inter-dependable. You don't need additional plug-ins or something related. Additionally, the XLS (Excel) file is supported for exporting and importing as well. The TXT and CSV file format can be used with other applications that are not from this application's category.
