DESCRIPTION

usage: csvformat [-h] [-d DELIMITER] [-t] [-q QUOTECHAR] [-u {0,1,2,3}] [-b]

[-p ESCAPECHAR] [-z FIELD_SIZE_LIMIT] [-e ENCODING] [-S] [-H] [-K SKIP_LINES] [-v] [-l] [--zero] [-V] [-D OUT_DELIMITER] [-T] [-Q OUT_QUOTECHAR] [-U {0,1,2,3}] [-B] [-P OUT_ESCAPECHAR] [-M OUT_LINETERMINATOR] [FILE]

Convert a CSV file to a custom output format.

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
-d DELIMITER, --delimiter DELIMITER: Delimiting character of the input CSV file.
-t, --tabs: Specify that the input CSV file is delimited with tabs. Overrides "-d".
-q QUOTECHAR, --quotechar QUOTECHAR: Character used to quote strings in the input CSV file.
-u {0,1,2,3}, --quoting {0,1,2,3}: Quoting style used in the input CSV file. 0 = Quote Minimal, 1 = Quote All, 2 = Quote Non-numeric, 3 = Quote None.
-b, --no-doublequote: Whether or not double quotes are doubled in the input CSV file.
-p ESCAPECHAR, --escapechar ESCAPECHAR: Character used to escape the delimiter if --quoting 3 ("Quote None") is specified and to escape the QUOTECHAR if --no-doublequote is specified.
-z FIELD_SIZE_LIMIT, --maxfieldsize FIELD_SIZE_LIMIT: Maximum length of a single field in the input CSV file.
-e ENCODING, --encoding ENCODING: Specify the encoding of the input CSV file.
-S, --skipinitialspace: Ignore whitespace immediately following the delimiter.
-H, --no-header-row: Specify that the input CSV file has no header row. Will create default headers (a,b,c,...).
-K SKIP_LINES, --skip-lines SKIP_LINES: Specify the number of initial lines to skip before the header row (e.g. comments, copyright notices, empty rows).
-v, --verbose: Print detailed tracebacks when errors occur.
-l, --linenumbers: Insert a column of line numbers at the front of the output. Useful when piping to grep or as a simple primary key.
--zero: When interpreting or displaying column numbers, use zero-based numbering instead of the default 1-based numbering.
-V, --version: Display version information and exit.
-D OUT_DELIMITER, --out-delimiter OUT_DELIMITER: Delimiting character of the output CSV file.
-T, --out-tabs: Specify that the output CSV file is delimited with tabs. Overrides "-D".
-Q OUT_QUOTECHAR, --out-quotechar OUT_QUOTECHAR: Character used to quote strings in the output CSV file.
-U {0,1,2,3}, --out-quoting {0,1,2,3}: Quoting style used in the output CSV file. 0 = Quote Minimal, 1 = Quote All, 2 = Quote Non-numeric, 3 = Quote None.
-B, --out-no-doublequote: Whether or not double quotes are doubled in the output CSV file.
-P OUT_ESCAPECHAR, --out-escapechar OUT_ESCAPECHAR: Character used to escape the delimiter in the output CSV file if --quoting 3 ("Quote None") is specified and to escape the QUOTECHAR if --no-doublequote is specified.
-M OUT_LINETERMINATOR, --out-lineterminator OUT_LINETERMINATOR: Character used to terminate lines in the output CSV file.
