DESCRIPTION
Renders a CSV to the command line in a Markdown-compatible, fixed-width format:
usage: csvlook [-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] [--max-rows MAX_ROWS] [--max-columns MAX_COLUMNS] [--max-column-width MAX_COLUMN_WIDTH] [--max-precision MAX_PRECISION] [--no-number-ellipsis] [-y SNIFF_LIMIT] [-I] [FILE] Render a CSV file in the console as a Markdown-compatible, fixed-width table. 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 --max-rows MAX_ROWS The maximum number of rows to display before truncating the data. --max-columns MAX_COLUMNS The maximum number of columns to display before truncating the data. --max-column-width MAX_COLUMN_WIDTH Truncate all columns to at most this width. The remainder will be replaced with ellipsis. --max-precision MAX_PRECISION The maximum number of decimal places to display. The remainder will be replaced with ellipsis. --no-number-ellipsis Disable the ellipsis if --max-precision is exceeded. -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 when parsing the input. This disables the reformatting of values.
If a table is too wide to display properly try piping the output to less -S or truncating it using csvcut.
If the table is too long, try filtering it down with grep or piping the output to less.

NOTE:
EXAMPLES
Basic use:
csvlook examples/testfixed_converted.csv
This tool is especially useful as a final operation when piping through other tools:
csvcut -c 9,1 examples/realdata/FY09_EDU_Recipients_by_State.csv | csvlook
If a data row contains more cells than the header row, csvlook will error. Use csvclean to remove such rows.
To ignore the extra cells, instead:
csvcut -C "" examples/bad.csv | csvlook
If these rows are at the top of the file (for example, copyright notices), you can skip the rows:
csvlook --skip-lines 1 examples/bad.csv
This error can also occur if csvlook incorrectly deduces ("sniffs") the CSV format. To disable CSV sniffing, set --snifflimit 0 and then, if necessary, set the --delimiter and --quotechar options yourself. Or, set --snifflimit -1 to use the entire file as the sample, instead of the first 1024 bytes.
