Question

我有一个我从商业系统下载的价格列，根据国家/地区，这些数字有不同的格式，例如：

1.260,14 -> this is seen as text by Excel
1,280.14 -> this is seen as text by Excel
1280.14  -> this is the only correct one, seen as number

我希望Power Query将所有内容转换为数字，在这种情况下，这意味着所有3个数字应该是：＆＃34; 1280.14＆＃34;

Answer 1

1）将您的列拆分为小数位：按字符数拆分列：2 - 尽可能远正确

2）第一栏：替换“。”通过“”（没有）

3）第一栏：将“，”替换为“”（无）

4）将两列合并为“。”作为分隔符并更改为十进制格式

Answer 2

如果您知道哪些文档来自哪个国家/地区，则在使用Table.TransformColumnTypes时也可以考虑区域设置。您可以右键单击该列，然后选择“更改类型”使用Locale ....这将产生类似Table.TransformColumnTypes(Step, {{"Column Name", Currency.Type}}, "locale name")。

Answer 3

这是一个Power Query函数，我只是将混合格式文本转换为数字。它将点或逗号的最后一次出现视为小数分隔符，只要该字符在文本中只出现一次。

要使用此功能，请转到“Power Query”功能区选项卡，单击“From Other Sources”＆gt; “空白查询”。然后转到“高级编辑器”并将下面的脚本复制粘贴到编辑器并保存。然后，您可以返回主查询并点击“添加列”＆gt; “添加自定义列”。 “=”之后的公式为：toNumber([column name])。

let

     toNumber = (text) =>

let

//remove characters that occur more than once as they can't be decimal separators
       text1 = if List.Count(Text.PositionOf(text, ",", Occurrence.All)) > 1
         then Text.Replace(text, ",", "") else text
,      text2 = if List.Count(Text.PositionOf(text1, ".", Occurrence.All)) > 1
         then Text.Replace(text1, ".", "") else text1

//if there are still more than one potential decimal separator, remove the kind that occurs first
//let's assume the last one is the actual decimal separator
,      text3 = if List.Count(Text.PositionOfAny(text2, {",","."}, Occurrence.All)) > 1
         then Text.Replace(text2, Text.At(text2, Text.PositionOfAny(text2, {",","."}, Occurrence.First)), "") 
         else text2

//cast as number (try different decimal separators)
,      number = 
  try       Number.ToText(Number.From(Text.Replace(text3,",","."))) 
  otherwise Number.ToText(Number.From(Text.Replace(text3,".",",")))

      number
in
    toNumber
