Description
===========
Converts a CSV file into JSON or GeoJSON (depending on flags):
.. code-block:: none
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 entirely, or
"-1" to sniff the entire file.
-I, --no-inference Disable type inference (and --locale, --date-format,
--datetime-format, --no-leading-zeroes) when parsing
the input.
