Subject: FEATURE REQUEST: Parse SEP= parameters used by Excel
Microsoft Excel has the ability to read the field separator used in a CSV file from a "sep=" parameter specified in the first line of that file. This will ensure that the file will be properly parsed no matter the separator specified by the locale settings. (See: https://social.technet.microsoft.com/Forums/office/en-US/ee8f0432-f7d4-4730-84f3-2814eca9c06a/csv-files-arent-delimined-when-opened?forum=excel) Unfortunately, Text::CSV_XS will read that line as a regular line in the CSV file and may alter it. (For instance, it will add quotes if "always_quote" is set to 1, which will break the functionality in Excel. I would suggest that Text::CSV_XS function csv::in should parse that line, use it to set the "sep_char" parameter, and remove the line from the stream provided by the module. Optionally, you could pass a new argument to the "csv" function that would add it back in before writing to a file using csv::out, adjusting it's value if sep_char has been changed.

Will be in version 1.17. Still need to write documentation and tests. Still in doubt if it ought to be enabled by default $ cat files/ms1203.csv sep=; "Ħēłļō Ẇȯṙŀḋ";CSV-1203 $ perl -Mblib -MCSV -e'dcsv(in=>"files/ms1203.csv")' [ [ "\x{126}\x{113}\x{142}\x{13c}\x{14d} \x{1e86}\x{22f}\x{1e59}\x{140}\x{1e0b}", 'CSV-1203' ] ]

Great news! Thanks! Let me know if I can help you test.

What would be the harm? The presence of that field pretty clearly indicates the author if the CSV file intends for it to be used. Not enabling it produces a stream with superfluous data. -- François Beaulieu (iPhone) (514) 667-0691 x2061

It is backwards incompatible. The old behavior was completely valid

not for people that expect that line to be valid :) Though I currently tend to make this the default behavior and make it an option if people start complaining -- H.Merijn Brand http://tux.nl Perl Monger http://amsterdam.pm.org/ using perl5.00307 .. 5.21 porting perl5 on HP-UX, AIX, and openSUSE http://mirrors.develooper.com/hpux/ http://www.test-smoke.org/ http://qa.perl.org http://www.goldmark.org/jeff/stupid-disclaimers/
