DESCRIPTION

9       Cleans a CSV file of common syntax errors:
10
11       • reports  rows that have a different number of columns than the header
12         row
13
14       • attempts to correct the CSV by joining short rows into a single row
15
16       Note that every csvkit tool does the following:
17
18       • removes optional quote characters, unless the –quoting (-u) option is
19         set to change this behavior
20
21       • changes the field delimiter to a comma, if the input delimiter is set
22         with the –delimiter (-d) or –tabs (-t) options
23
24       • changes the record delimiter to a line feed (LF or \n)
25
26       • changes the quote character to a double-quotation mark, if the  char‐
27         acter is set with the –quotechar (-q) option
28
29       • changes the character encoding to UTF-8, if the input encoding is set
30         with the –encoding (-e) option
31
32       Outputs [basename]_out.csv and [basename]_err.csv, the former  contain‐
33       ing  all valid rows and the latter containing all error rows along with
34       line numbers and descriptions:
35

37                          [-p ESCAPECHAR] [-z FIELD_SIZE_LIMIT] [-e ENCODING] [-S] [-H]
38                          [-K SKIP_LINES] [-v] [-l] [--zero] [-V] [-n]

42
43          positional arguments:
44            FILE                  The CSV file to operate on. If omitted, will accept
45                                  input on STDIN.
46
47          optional arguments:
48            -h, --help            show this help message and exit
49            -n, --dry-run         Do not create output files. Information about what
50                                  would have been done will be printed to STDERR.

EXAMPLES

55       Test a file with known bad rows:
56
57          csvclean -n examples/bad.csv
58
59          Line 1: Expected 3 columns, found 4 columns
60          Line 2: Expected 3 columns, found 2 columns
61
62       To change the line ending from line feed (LF or \n) to carriage  return
63       and line feed (CRLF or \r\n) use:
64
65          csvformat -M $'\r\n' examples/dummy.csv
