DESCRIPTION

       Converts a CSV file into JSON or GeoJSON (depending on flags):

          usage: csvjson [-h] [-d DELIMITER] [-t] [-q QUOTECHAR] [-u {0,1,2,3}] [-b]
                         [-p ESCAPECHAR] [-z FIELD_SIZE_LIMIT] [-e ENCODING] [-L LOCALE]
                         [-S] [--blanks] [--null-value NULL_VALUES [NULL_VALUES ...]]
                         [--date-format DATE_FORMAT] [--datetime-format DATETIME_FORMAT]
                         [-H] [-K SKIP_LINES] [-v] [-l] [--zero] [-V] [-i INDENT]
                         [-k KEY] [--lat LAT] [--lon LON] [--type TYPE]
                         [--geometry GEOMETRY] [--crs CRS] [--no-bbox] [--stream]
                         [-y SNIFF_LIMIT] [-I]
                         [FILE]

          Convert a CSV file into JSON (or GeoJSON).

          positional arguments:
            FILE                  The CSV file to operate on. If omitted, will accept
                                  input as piped data via STDIN.

          optional arguments:
            -h, --help            show this help message and exit
            -i INDENT, --indent INDENT
                                  Indent the output JSON this many spaces. Disabled by
                                  default.
            -k KEY, --key KEY     Output JSON as an object keyed by a given column, KEY,
                                  rather than as an array. All column values must be
                                  unique. If --lat and --lon are specified, this column
                                  is used as the GeoJSON Feature ID.
            --lat LAT             A column index or name containing a latitude. Output
                                  will be GeoJSON instead of JSON. Requires --lon.
            --lon LON             A column index or name containing a longitude. Output
                                  will be GeoJSON instead of JSON. Requires --lat.
            --type TYPE           A column index or name containing a GeoJSON type.
                                  Output will be GeoJSON instead of JSON. Requires --lat
                                  and --lon.
            --geometry GEOMETRY   A column index or name containing a GeoJSON geometry.
                                  Output will be GeoJSON instead of JSON. Requires --lat
                                  and --lon.
            --crs CRS             A coordinate reference system string to be included
                                  with GeoJSON output. Requires --lat and --lon.
            --no-bbox             Disable the calculation of a bounding box.
            --stream              Output JSON as a stream of newline-separated objects,
                                  rather than an as an array.
            -y SNIFF_LIMIT, --snifflimit SNIFF_LIMIT
                                  Limit CSV dialect sniffing to the specified number of
                                  bytes. Specify "0" to disable sniffing.
            -I, --no-inference    Disable type inference (and --locale, --date-format,
                                  --datetime-format) when parsing CSV input.
