openrefine - 将多列中的多值单元格拆分为行(打开优化)

Question

我一直在 Open Refine 上清理 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 中拆分这些多值单元格，以便得到:

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

可以在 Open Refine 中执行此操作吗？ “拆分多值单元格...”命令仅处理一列。谢谢你，安娜丽塔

Answer 1

是的，这是可能的:

• 使用“,”作为分隔符拆分第一列。
• 将第 2 列移至位置 1
• 将您的项目显示为记录(而不是行)
• 使用“,”作为分隔符拆分第 3 列
• 填写第 4 栏和第 2 栏
• 对列重新排序

这是我在 GREL 中的食谱:
