    I am not sure exactly what you are trying to do, but SQLiteStudio does
provide you the ability to export as CSV.  Are you trying to export just
the table or the table + table indexes + table triggers?  CSV export is
supported under Data ->Export only for table export (not for table +
indexes or table + triggers, etc.).

    If you are trying to export the whole database, it is best to think of
a database with multiple tables as a spreadsheet with multiple tabs.  You
can export each tab as a CSV, but you can't export an entire multi-tab
spreadsheet as one CSV.  Same thing applies to databases.  You can either
export each table as a CSV, then import them into multiple tabs of a
spreadsheet and use vlookups to relate the data into one bigger dataset
with more columns - or better yet, write some SQL to "join" the tables and
export the results of that query as a CSV for import into a spreadsheet.
