You can very easily download data in CSV format from Watch My Domains SED v4. The download options are available for both domain and report tables. Please see the screen shot below.
The download can be scheduled as a background task when the number of rows is more than 5000. You can select the rows and columns that appear in the download. You may also specify the column delimiter (between comma, semicolon and tab).
You may need to use the data import option in Excel to open the downloaded file in Excel.
