To download Freestyle Libre 2 data to a computer, you need to use the LibreView website, which serves as the central hub for storing and reviewing your glucose history. Whether you use the FreeStyle Libre 2 reader device or the FreeStyle LibreLink app, your data can be accessed through LibreView for personal review or to share with a healthcare provider.
What you need to download freestyle libre 2 data
Before you begin, ensure your computer meets the system requirements. LibreView Device Drivers require Windows 8.1 or 10 (April 2018 update or higher) or macOS Big Sur (11) or higher, along with 8 GB+ RAM and 200 MB free disk space. You also need an internet connection with at least 1 Mbps upload speed and a local Administrator account for driver installation.
You must first create or log in to a LibreView account at LibreView.com. The process differs depending on your device: if you use the FreeStyle LibreLink app, glucose data is automatically uploaded to LibreView every time you scan your FreeStyle Libre 2 sensor, provided there is an internet connection. If you use the FreeStyle Libre 2 Reader, you will need to download device drivers and connect the reader to your computer with a cable.
Installing the LibreView device drivers
To download data from the FreeStyle Libre 2 Reader, you need to download and install the LibreView Device Drivers on your computer. This step is essential so your computer can recognize the reader when it is connected.
- Go to the LibreView website and navigate to the drivers section.
- Select the driver version for your operating system (Windows or Mac).
- Download the driver installation file to your computer.
- Run the installation file. You must be logged in with a local Administrator account to complete the installation.
- Follow the on-screen prompts to finish the setup.
An internet connection with 1 Mbps upload speed is required for driver installation and data upload. After installation, you are ready to connect your reader.
Connecting your FreeStyle Libre 2 reader to the computer
Connect your FreeStyle Libre 2 Reader to your computer using a compatible data cable, typically a micro-USB cable. Plug one end into the reader and the other into a USB port on your computer. Launch the LibreView website and log in to your account. The site will detect the connected reader once the drivers are properly installed.
Uploading glucose data to LibreView
After installing drivers and connecting the reader, click the "Press to Begin Upload" button on the LibreView "Upload Device" screen. The transfer will begin automatically. It is recommended to upload your FreeStyle Libre 2 Reader data at least once every 90 days to avoid data loss.
Viewing and analyzing your glucose history
Once the upload finishes, your data appears on the LibreView dashboard. Here you can view glucose trends, daily patterns, and historical reports. The LibreView software is intended for reviewing, analyzing, and evaluating historical glucose data and is not for treatment decisions or as a substitute for professional healthcare advice. Use the dashboard to identify patterns and share insights with your healthcare provider.
Exporting data as a CSV file
To export data from LibreView as a CSV file, log in to LibreView.com and navigate to "Glucose History." Click the "Download Glucose Data" icon, which looks like an arrow pointing downwards. Complete the CAPTCHA to confirm you are not a robot, then click the blue "Download" box. The CSV file will save to your computer, ready for sharing with healthcare providers or keeping as a personal record.
