将多列中的多值单元格拆分成行（打开优化）

Question

我一直在清理 Open Refine 上的 table。我现在是这样的：

REF                 Handle      Size        Price
2002, 2003          t-shirt1    M, L        23
3001, 3002, 3003    t-shirt2    S, M, L     24

我需要在 REF 和 Size 中拆分那些多值单元格，以便我得到：

REF                 Handle      Size        Price
2002                t-shirt1    M           23
2003                t-shirt1    L           23  
3001                t-shirt2    S           24  
3002                t-shirt2    M           24
3003                t-shirt2    L           24

是否可以在 Open Refine 中执行此操作？ "Split multi-valued cells..." 命令只处理一列。谢谢，安娜丽塔

Answer 1

是的，有可能：

使用“,”作为分隔符拆分第一列。
将第 2 列移到第一个位置
将您的项目显示为记录（不是行）
使用“,”作为分隔符拆分第 3 列
填写第 4 列和第 2 列
重新排列列

这是我在 GREL 中的食谱：

刚刚找到一个不错的免费 OpenRefine 插件，它提供“不成对的枢轴”： VIB-Bits plugin

来自 their documentation:

3.2.1 不成对的枢轴... Unpaired pivot 是将按行组织的数据转换为该行的表示单独列中的数据。一个简单的例子是转换

Category	Value
a	1
a	2
b	3
c	2

进入

Value a	Value b	Value c
1	3	2
2
