+To export table data to a CSV file, use the sequence of SQLite commands below:
+Ex: exporting Table nlbse_tool_competition_data_by_issue to a CSV file.
+```
+sqlite3 skillscope_data.db 
+.headers on
+.mode csv
+.output output.csv
+SELECT * FROM nlbse_tool_competition_data_by_issue;
+.quit
+```
+Important: CSV file will have zero bytes until you use the ```.quit``` statement !
+
+
+Alternatively, you can simply call sqlite3 and check the available tables.
+The statement ```.table``` will list the available tables.
+
+```
+sqlite3
+.tables
+.open skillscope_data.db
+```
