【Perl】与【Excel】

引言

perl脚本语言对于文本的处理、转换很强大。对于一些信息量庞大的文本文件，看起来不直观，可以将信息提取至excel表格中，增加数据分析的可视化。perl语言的cpan提供了大量模块。对于excel文件的操作主要用到模块：

Spreadsheet::ParseXLSX

Excel::Writer::XLSX

第一个用于对现有excel 表格的解析，第二个用于创建新的excel文件。如果单纯是将文本信息提取到excel表格中其实第二个模块用的更多。看自己需求吧。

模块安装

首先确保你的linux系统有perl。

安装模块的指令 sudo perl -MCPAN -e “install ‘模块名'”

sudo perl -MCPAN -e “install ‘Spreadsheet::ParseXLSX'”

sudo perl -MCPAN -e “install ‘Excel::Writer::XLSX'”
