If you have enrolled for a Basic Suite or higher you can download your Website Success reports at any time as CSV files.
To do so you can simply use the export function you can find with every Website Success report. The CSV export is capped at 100k rows. Aside from CSV files you can also export the data as an Excel file, JSON file or XML file (30k rows). Customers with Business packages can also use an uncapped API call to export the data.
