The standard solution for handling files containing character-separated values (CSV), including tabulator separated values, is to use Text::CSV and - if possible - its accelerating companion Text::CSV_XS. It is "the standard" because it not only splits (and joins) on the separating character(s), but also handles quoting, escaping, and all of those nasty edge cases you can find in CSV files.

If you are used to work with relational databases and DBI, try DBD::CSV. It sits on top of Text::CSV and allows you to treat CSV files like database tables in a relational database. In other words: You can use SQL to work directly with CSV files.

All of those modules are currently maintained by our helpful Tux.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
