Question

我一直在Open Refine上清理一张桌子。我现在有这样的话：

var dataURL = canvas.toDataURL({
                format: 'png',
                multiplier: 20
            })

            var pdf = new jsPDF();
            pdf.addImage(dataURL, 'PNG', 0, 0);
            pdf.save("download.pdf");
        }

我需要在REF和Size中拆分那些多值单元格，以便得到：

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

是否可以在Open Refine中执行此操作？＆＃34;拆分多值单元格......＆＃34;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1列。
将第2列移至第1位
将您的项目显示为记录（不是行）
使用“，”作为分隔符
填写第4栏和第2栏
重新排序列

这是我在GREL中的食谱：

Answer 2

刚刚找到了一个不错的免费 OpenRefine 插件，它提供了“未配对的枢轴”： VIB-Bits plugin

来自their documentation：

3.2.1 未配对枢轴... 未配对数据透视是将按行组织的数据转换为该数据的表示单独列中的数据。一个简单的例子是转换

<头>

类别	价值
一	1
一	2
b	3
c	2

进入

<头>

值a	值 b	值 c
1	3	2
2

将多个列中的多值单元格拆分为多行（Open Refine）
