bw2io.export.write_lci_csv(database_name, objs=None, sections=None, dirpath=None)[source]#

Export database database_name to a CSV file.

Not all data can be exported. The following constraints apply:

  • Nested data, e.g. {‘foo’: {‘bar’: ‘baz’}} are excluded. CSV is not a great format for nested data. However, tuples are exported, and the characters :: are used to join elements of the tuple.

  • The only well-supported data types are strings, numbers, and booleans.

Default directory is projects.output_dir, set dirpath to have save the file somewhere else.

Returns the filepath of the exported file.
