# Example of how to use the WriteExcel module
#
# Simple program to convert a CSV comma-separated value file to an Excel file.
# This is more or less an non-op since Excel can read CSV files.
# The program uses Text::CSV_XS to parse the CSV.
#
# Usage: csv2xls.pl file.csv newfile.xls
#
#
# NOTE: This is only a simple conversion utility for illustrative purposes.
# For converting a CSV or Tab separated or any other type of delimited
# text file to Excel I recommend the more rigorous csv2xls program that is
# part of H.Merijn Brand's Text::CSV_XS module distro.
#
# See the examples/csv2xls link here:
#     http://search.cpan.org/~hmbrand/Text-CSV_XS/MANIFEST
