While importing products (somewhere around 1200 rows) by Magento’s in-built “System > Import/Export > Dataflow – Profiles” I got an error where the Dashboard’s HTML was printed in the output.

The reason for this error is due to something wrong in CSV product data which Magento didn’t understand. Create a temporary CSV file with only few rows (2-4) and check if that works. If it works, that means there is some problem with rest of the data.
