9 Converts various tabular data formats into CSV.
10
11 Converting fixed width requires that you provide a schema file with the
12 “-s” option. The schema file should have the following format:
13
14 column,start,length
15 name,0,30
16 birthday,30,10
17 age,40,3
18
19 The header line is required though the columns may be in any order:
20
21 usage: in2csv [-h] [-d DELIMITER] [-t] [-q QUOTECHAR] [-u {0,1,2,3}] [-b]
22 [-p ESCAPECHAR] [-z FIELD_SIZE_LIMIT] [-e ENCODING] [-L LOCALE]
23 [-S] [--blanks] [--date-format DATE_FORMAT]
24 [--datetime-format DATETIME_FORMAT] [-H] [-K SKIP_LINES] [-v]
25 [-l] [--zero] [-V] [-f FILETYPE] [-s SCHEMA] [-k KEY] [-n]
26 [--sheet SHEET] [--write-sheets WRITE_SHEETS]
27 [--encoding-xls ENCODING_XLS] [-y SNIFF_LIMIT] [-I]

30 Convert common, but less awesome, tabular data formats to CSV.
31
32 positional arguments:
33 FILE The CSV file to operate on. If omitted, will accept
34 input as piped data via STDIN.
35
36 optional arguments:
37 -h, --help show this help message and exit
38 -f {csv,dbf,fixed,geojson,json,ndjson,xls,xlsx}, --format {csv,dbf,fixed,geojson,json,ndjson,xls,xlsx}
39 The format of the input file. If not specified will be
40 inferred from the file type.
41 -s SCHEMA, --schema SCHEMA
42 Specify a CSV-formatted schema file for converting
43 fixed-width files. See web documentation.
44 -k KEY, --key KEY Specify a top-level key to look within for a list of
45 objects to be converted when processing JSON.
46 -n, --names Display sheet names from the input Excel file.
47 --sheet SHEET The name of the Excel sheet to operate on.
48 --write-sheets WRITE_SHEETS
49 The names of the Excel sheets to write to files, or
50 "-" to write all sheets.
51 --encoding-xls ENCODING_XLS
52 Specify the encoding of the input XLS file.
53 -y SNIFF_LIMIT, --snifflimit SNIFF_LIMIT
54 Limit CSV dialect sniffing to the specified number of
55 bytes. Specify "0" to disable sniffing.
56 -I, --no-inference Disable type inference (and --locale, --date-format,
57 --datetime-format) when parsing CSV input.
58
59 Some command-line flags only pertain to specific input formats.
60
61 See also: Arguments common to all tools.
62
63 NOTE:
64 The “ndjson” format refers to “newline delimited JSON”, as used by
65 many streaming APIs.
66
67 NOTE:
68 If an XLS looks identical to an XLSX when viewed in Excel, they may
69 not be identical as CSV. For example, XLSX has an integer type, but
70 XLS doesn’t. Numbers that look like integers from an XLS will have
71 decimals in CSV, but those from an XLSX won’t.
72
73 NOTE:
74 To convert from HTML, consider messytables.
75
77 Convert the 2000 census geo headers file from fixed-width to CSV and
78 from latin-1 encoding to utf8:
79
80 in2csv -e iso-8859-1 -f fixed -s examples/realdata/census_2000/census2000_geo_schema.csv examples/realdata/census_2000/usgeo_excerpt.upl
81
82 NOTE:
83 A library of fixed-width schemas is maintained in the ffs project:
84
85 https://github.com/wireservice/ffs
86
87 Convert an Excel .xls file:
88
89 in2csv examples/test.xls
90
91 Standardize the formatting of a CSV file (quoting, line endings, etc.):
92
93 in2csv examples/realdata/FY09_EDU_Recipients_by_State.csv
94
95 Fetch csvkit’s open issues from the GitHub API, convert the JSON re‐
96 sponse into a CSV and write it to a file:
97
98 curl https://api.github.com/repos/wireservice/csvkit/issues?state=open | in2csv -f json -v
99
100 Convert a DBase DBF file to an equivalent CSV:
101
102 in2csv examples/testdbf.dbf
103
104 This tool names unnamed headers. To avoid that behavior, run:
105
106 in2csv --no-header-row examples/test.xlsx | tail -n +2
