Extract first 4 digits from postcode from text column
Hi, I have a column which has full addresses in it which due to the various ways the addresses have been handed over from the client I can't use the extract by delimiter function. I would like t...
deefunk1981 , One way is to search position of BT and then take 4 character
mid([column], search("BT",[Column],,len([Column])), 4)
Steps to follow:
1- Create a new column (by right clicking on a table and selecting new column option) and use the calculation given by amitchandaknew_Column = mid([column1], search(" BT",[Column1],,len([Column1])), 4)
this will give you a new column with the first 4 digits of your postcode.search(" BT"...) is going to search in your text if " BT" is there. If it is there then it will take first 4 characters(for which we have used ",4" in the formula) from BT to the right including BT.
Try using this M code:
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("bc29DoIwFIbhW/nC3IE/RUeMuqiEAMYBGRp6Io21NccS4t1rdNTxHZ68bRtsjfSIIxyI+0Fa/0DvRvYCGzVJVqg9E72zoImfAqsmmWGeFwJHqz0p7LS9KHcLOtEGSYh6IDLaopR8FdifxzCMszXx16YLLPPyr40yVG6SxjiLSgmcJDPZu9PWf64pkqb6ld0L", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [project.address_full = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"project.address_full", type text}}),
#"Duplicated Column" = Table.DuplicateColumn(#"Changed Type", "project.address_full", "project.address_full - Copy"),
#"Inserted Text Before Delimiter" = Table.AddColumn(#"Duplicated Column", "Text Before Delimiter", each Text.BeforeDelimiter([#"project.address_full - Copy"], ", United Kingdom"), type text),
#"Inserted Last Characters" = Table.AddColumn(#"Inserted Text Before Delimiter", "Last Characters", each Text.End([Text Before Delimiter], 8), type text),
#"Inserted First Characters" = Table.AddColumn(#"Inserted Last Characters", "First Characters", each Text.Start([Last Characters], 4), type text),
#"Removed Columns" = Table.RemoveColumns(#"Inserted First Characters",{"project.address_full - Copy", "Text Before Delimiter", "Last Characters"})
in
#"Removed Columns"
