When you are using remote desk connection, open browser there and navigate to CSV2QBO page and download the installer. Start the installer and confirm elevated admin privileges. If you need to contact your admin to install the software, please do this. If it takes more time to contact your admin, try to download portable version that does not require the installation - simply unzip the download and run it.
Once you start CSV2QBO, select CSV or Excel file on the file dialog, and review transactions. If your CSV file does not have the column header, click Review mapping to map the columns if needed. Click the Convert button to create the QBO file.
In QuickBooks, select File-Utilities-Import-Web Connect file... and point to the QBO file.
