这适用于 powerquery (M)

假设数据来自 Table1，进入 Column 1 如果不正确，请调整代码

它还假定结尾 ~ 和下一个单词之间有一个 space

 let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
 #"Replaced Value" = Table.ReplaceValue(Source,"~ ","::",Replacer.ReplaceText,{"Column1"}),
 #"Adjust edge case" = Table.TransformColumns(#"Replaced Value",{{"Column1", each if Text.End(_,1)="~" then Text.Start(_,Text.Length(_)-1) &"::" else _, type text}}),
 #"Added Custom" = Table.AddColumn(#"Adjust edge case", "Custom", each List.Difference(List.Transform(Text.Split([Column1],"~"), each Text.BeforeDelimiter(_,"::")),{""})),
 ColumnNames=List.Transform({1..List.Max(List.Transform(#"Added Custom"[Custom], each List.Count(_)))}, each "Data "&Text.From(_)),
 #"Added Custom2" = Table.AddColumn(#"Adjust edge case", "Custom", each Text.Combine(List.Skip(List.Transform(Text.Split([Column1],"~"), each Text.BeforeDelimiter(_,"::")),1),"~")),
 #"Split Column by Delimiter" = Table.SplitColumn(#"Added Custom2", "Custom", Splitter.SplitTextByDelimiter("~", QuoteStyle.Csv), ColumnNames)
 in  #"Split Column by Delimiter"
