Hello everyone, Would appreciate some hints on how to replace multiple values (ideally from another mapping table).
The challenge I'm facing is: to replace several values in two columns ("Column 1","Column 2"), I used a stupid way to use several ReplaceValue lines and pls find a sample as below:
#"Replaced Value1" = Table.ReplaceValue(#"Added Custom1","Ltd.","",Replacer.ReplaceText,{"Column 1","Column 2"}),
#"Replaced Value2" = Table.ReplaceValue(#"Replaced Value1","Co.","",Replacer.ReplaceText,{"Column 1","Column 2"}),
#"Replaced Value3" = Table.ReplaceValue(#"Replaced Value2","China","CN",Replacer.ReplaceText,{"Column 1","Column 2"}), #"Replaced Value4" = Table.ReplaceValue(#"Replaced Value3","CHN","CN",Replacer.ReplaceText,{"Column 1","Column 2"}), #"Replaced Value5" = Table.ReplaceValue(#"Replaced Value4","(","",Replacer.ReplaceText,{"Column 1","Column 2"}),
#"Replaced Value6" = Table.ReplaceValue(#"Replaced Value5",")","",Replacer.ReplaceText,{"Column 1","Column 2"}),
...
Is there a simple way that I can put all replacement values to a mapping table (from "Ltd." to "", from "Co." to "", etc), and in the future, I can easily add more mapping values? thanks a lot.
Simple enough, use embedded Table.ReplaceValue().
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8ilJ0VPSUXLO11OK1YFwFUAcoJCHH1jIOSMzLxHI19RUcIEIACV0lDRASjXBAo5OzgoaQE2aQOH8ikKwWEREBMgMsN7YWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t]),
Replacement = {
{{"Ltd.","Co.","(",")"}, ""}
, {{"China","CHN"}, "CN"}
},
Replaced = List.Accumulate(Replacement, Source, (s,c) => Table.ReplaceValue(s, c{0}, c{1}, (x,y,z) => List.Accumulate(y, x, (s,c) => Text.Replace(s, c, z)), {"Column1","Column2"}))
in
Replaced
Expertise = List.Accumulate( {Days as from Today}, {Skills and Knowledge}, (Current, Everyday) => Current & Day.LearnAndPractise(Everyday) ) |
Hi @Rozan
You could probably be able to use fuzzy merge https://learn.microsoft.com/en-us/power-query/merge-queries-fuzzy-match and be able to use a mapping table too.
