Go to the System → Data → Export
Export helps to get quick access to any database table or record in the database and receive easy to read XML, CSV or TXT formats. Similar way, XML, CSV or TXT records can be saved back to the database.
In a comma-separated values (CSV) file the data items are separated using commas as a delimiter, while in a tab-separated values file, the data items are separated using tabs as a delimiter. Select what is best fit to your editor or import tool
it is recommended to select only data your need for export. If you select all tables a lot of unnecessary columns will be added to your CSV file and this will make your editing more complicated
