什么'；使用Perl或Ruby提取Excel单元格注释的最佳方法是什么？
我一直在用Perl成功解析Excel文档（如中所建议），但我不知道如何提取单元格注释什么'；使用Perl或Ruby提取Excel单元格注释的最佳方法是什么？,ruby,perl,excel,parsing,Ruby,Perl,Excel,Parsing,我一直在用Perl成功解析Excel文档（如中所建议），但我不知道如何提取单元格注释 有什么想法吗？Perl或Ruby的解决方案是理想的。一个选项是使用Ruby的win32ole库 下面的示例（有些冗长）连接到打开的Excel工作表，并从单元格B2获取注释文本 require 'win32ole' xl = WIN32OLE.connect('Excel.Application') ws = xl.ActiveSheet cell = ws.Range('B2') comment = cell

require 'win32ole'
xl = WIN32OLE.connect('Excel.Application')
ws = xl.ActiveSheet
cell = ws.Range('B2')
comment = cell.Comment
text = comment.Text
xlrd.sheet.OBJ_MSO_DEBUG我不确定ParseExcel是否可以用于此，但我将研究它。同时，你能在Windows上运行这个程序吗？你是否安装了Excel？如果两个答案都是“是”，则可以使用Win32:：OLE完成此操作。@OP:请记住，如果您真的愿意，可以从Perl中的内联：：Python完成此操作！
