Calling the program like so:

$ in2csv --key items customers-page-1.json > customer.csv

Produces:

$ cat customer.csv 
id,firstName,lastName,fullName,photoUrl,photoType,gender,age,organization,jobTitle,location,createdAt,modifiedAt
74798241,Edyth,U.,Edyth U.,,,unknown,,,,,2016-03-02T04:26:52Z,2016-03-02T04:26:52Z

You should specify the key under which there is a list objects to make into the rows of CSV. In this particular case, items:

in2csv -k items test.json

As a general hint, if you run a command without arguments, you will get short usage, and longer with --help switch:

% in2csv
usage: in2csv [-h] [-d DELIMITER] [-t] [-q QUOTECHAR] [-u {0,1,2,3}] [-b]
              [-p ESCAPECHAR] [-z MAXFIELDSIZE] [-e ENCODING] [-S] [-H] [-v]
              [-l] [--zero] [-f FILETYPE] [-s SCHEMA] [-k KEY] [-y SNIFFLIMIT]
              [--sheet SHEET] [--no-inference]
              [FILE]
in2csv: error: You must specify a format when providing data via STDIN (pipe).

and

% in2csv --help
usage: in2csv [-h] [-d DELIMITER] [-t] [-q QUOTECHAR] [-u {0,1,2,3}] [-b]
              [-p ESCAPECHAR] [-z MAXFIELDSIZE] [-e ENCODING] [-S] [-H] [-v]
              [-l] [--zero] [-f FILETYPE] [-s SCHEMA] [-k KEY] [-y SNIFFLIMIT]
              [--sheet SHEET] [--no-inference]
              [FILE]

Convert common, but less awesome, tabular data formats to CSV.
....
  -k KEY, --key KEY     Specifies a top-level key to use look within for a
                        list of objects to be converted when processing JSON.
