( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Hi,

Here is what I am trying to do.

Read the CSV (excel sheet saved as a comma separated file) file into a perl data structure (either hash of array OR array of arrays). And sort based on one of the columns. When this is done, I want the rest of the columns too to be re-ordered based on the sorted column. That is the columns of a row must remain same.

For eg: This is the CSV file.
Name,Score,State
Mike,67,CA
Rob,63,FL
Jim,72,IL
Chan,32,AZ

When this is read into a perl data structure, and suppose I sort the column for Score in ascending order, I want the rest of the fields corresponding to the column to be re-ordered. So the result should be

Chan,32,AZ
Rob,63,FL
Mike,67,CA
Jim,72,IL

1. What data structure is best suited for above?
2. And how to achieve the above?

Thanks in advance.

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
