                        https://developers.google.com/workspace/guides/create-
                        credentials#create_a_service_account and share read
                        access sheets you want to export. (default: None)
  -f, --force           Tell this app tp overwrite existing files if present.
                        (default: False)
  -b BUFFER_LINES, --buffer-lines BUFFER_LINES
                        Maximum number of lines to retreive by http calls.
                        (default: 500)
  spreadsheet           Id of the spreadsheet you want to export to csv.
                        Spreadsheet id is the weird data present in the uri
                        just after `d/`:
                        https://docs.google.com/spreadsheets/d/<the
                        spreadsheet id is here>/
  selector              Sheet selector is a regex expression to match sheets
                        titles. Some examples: - `.*`: would export all sheets
                        - `(abcd)|(efgh)`: would export abcd and efgh sheets
  directory             Output directory with write access where csv files
                        will bewritten.

Logging params:
  --logging-file LOGGING_FILE
                        Logging configuration file, (logging-level and
                        logging-format are ignored if provide) (default: None)
  --logging-level LOGGING_LEVEL
  --logging-format LOGGING_FORMAT

This will create a .csv file per sheet with title match with the regex
expression.

Authentication

There are two ways to let this program access to your google sheets:

• You can provide google service account credentials with --service-account-credential-file option.

• By default script will open your browser that let you authorize (or not) readonly access to all your Google Sheets documents to this application which is running on your computer. An authorization token will be saved in your home directory: .gs-to-csv-token.json (You can control that path using GS_TO_CSV_TOKEN_FILE_PATH env variable)

Behavior (limitations)

• Google sheets API give a columnCount value which is a bit useless as we get extra cells. So for convenience this return, for each row, the same number of cells as the first line (expected header line!) which can result with empty lines or truncated data.

• lines without any values do not return blank line even in the middle of the sheet.
