Excel::ValueWriter::XLSX - generating data-only Excel workbooks in XLSX format, fast my $writer = Excel::ValueWriter::XLSX->new; $writer->add_sheet($sheet_name1, $table_name1, [[qw/a b/], [1, 2], [3, 4]]); $writer->add_sheet($sheet_name2, $table_name2, $row_generator); $writer->save_as($filename); The common way for generating Microsoft Excel workbooks in C format from Perl programs is the excellent L module. That module is very rich in features, but quite costly in CPU and memory usage. By contrast, the present module L is aimed at fast and cost-effective production of data-only workbooks, containing nothing but plain values. Such workbooks are useful in architectures where Excel is used merely as a local database, for example in connection with a PowerBI architecture.
