# Exporting data from the database

Before exporting data, always perform a data quality check and correct any data errors that you find. We recommend using the HelicsWin.Net data quality check functionality to help you achieve this (see Section 0).

You can export in the original Access database format (as an .mdb file compressed in a ZIP file) or in the TESSy CSV format.
