You can export data from BlueFolder by going to Settings > Import/Export > Export. Choose a dataset to be exported. After choosing a dataset, you'll see a list of filtering options. If you don't choose to filter the data, all relevant records will be included in the export file.
The file can be saved in an Excel, .csv, or .txt format. It is meant for record-keeping and data analysis only. If you want to export a file and then import it into QuickBooks, go to the Billing tab.
