使用Perl或Ruby提取Excel单元格注释的最佳方法是什么？

我一直在使用Spreadhsheet :: ParseExcel成功parsingPerl文档（正如在Perl中parsingExcel文件的最佳方法是什么？ ），但是我不知道如何提取单元格注释。

有任何想法吗？ 在Perl或Ruby中的解决scheme将是理想的。

Answer 1

一个select是使用Ruby的win32ole库。

以下（稍微详细）示例连接到打开的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.Comment text = comment.Text

Answer 2

Python xlrd库将parsing单元格注释（如果打开xlrd.sheet.OBJ_MSO_DEBUG ，您将看到它们），但是它不会从API公开它们。 你可以parsing转储或者对它进行一些破解，这样你就可以通过编程的方式获得它们。 这是一个开始（testing极其微小）：

那么你可以写一些像：

 import xlrd xlrd.sheet.OBJ_MSO_DEBUG = True xls = xlrd.open_workbook('foo.xls') for sheet in xls.sheets(): print 'sheet %s (%dx %d)' % (sheet.name, sheet.nrows, sheet.ncols) for rownum in xrange(sheet.nrows): for cell in sheet.row(rownum): print cell, cell.note
