Exporting and visualizing data

Use Foxglove Data Platform's web console to export your data as MCAP (.mcap) or ROS 1 (.bag) files and to visualize it in Foxglove Studio.

Once you've imported data to Foxglove Data Platform, you can export parts of it as a file or stream the data directly to debugging and visualization tools like Foxglove Studio.
