Maintainer(s)' notes

If you are reporting a bug in Spreadsheet::ParseExcel here are some pointers

1) State the issues as clearly and as concisely as possible. A simple program or Excel test file (see below) will often explain the issue better than a lot of text.

2) Provide information on your system, version of perl and module versions. The following program will generate everything that is required. Put this information in your bug report.

    #!/usr/bin/perl -w

    print "\n    Perl version   : $]";
    print "\n    OS name        : $^O";
    print "\n    Module versions: (not all are required)\n";

    my @modules = qw(
                      Spreadsheet::ParseExcel
                      Scalar::Util
                      Unicode::Map
                      Spreadsheet::WriteExcel
                      Parse::RecDescent
                      File::Temp
                      OLE::Storage_Lite
                      IO::Stringy
                    );

    for my $module (@modules) {
        my $version;
        eval "require $module";

        if (not $@) {
            $version = $module->VERSION;
            $version = '(unknown)' if not defined $version;
        }
        else {
            $version = '(not installed)';
        }

        printf "%21s%-24s\t%s\n", "", $module, $version;
    }

    __END__

3) Upgrade to the latest version of Spreadsheet::ParseExcel (or at least test on a system with an upgraded version). The issue you are reporting may already have been fixed.

4) Create a small example program that demonstrates your problem. The program should be as small as possible. A few lines of codes are worth tens of lines of text when trying to describe a bug.

5) Supply an Excel file that demonstrates the problem. This is very important. If the file is big, or contains confidential information, try to reduce it down to the smallest Excel file that represents the issue. If you don't wish to post a file here then send it to me directly: jmcnamara@cpan.org

6) Say if the test file was created by Excel, OpenOffice, Gnumeric or something else. Say which version of that application you used.

7) If you are submitting a patch you should check with the maintainer whether the issue has already been patched or if a fix is in the works. Patches should be accompanied by test cases.

Subject: Massive memory use when Import excel workbooks
Download (untitled) / with headers
text/plain 383b
When you attempt to process an excel file, In this case a 12Meg file, Ram consumption on the perl interpreter jumps to over 600 Meg. If you attempt to open subsequent files in the same program, there is an additive affect on consumption, though not to the same rate. The largest I've gotten it to expand too is 1.2 Gig. With sequencial file opens all smaller then 13 Meg a piece.

How about use CellHandler with NotSetCell => 1? (cf. dmpExH.pl of the distribution)

Hi, See the following: Reducing the memory usage of Spreadsheet::ParseExcel http://www.perlmonks.org/index.pl?node_id=379743 John. --
