Zip code to place

[kyliemcpoland]

We have data that contains the 5 digit zip codes. Is there a way to transform these numbers into the name of the city.

Hi @kyliemcpoland, if you find web page with your_country zip codes - you can do something like this. This is for Slovakia for example:

The code is not so simple, because I had to use Fn_Unzip (the reason is that I've found Slovakian zip codes only zipped version available online).

let
    Fn_Unzip =
        (ZIPFile) =>
        let
            Header = BinaryFormat.Record([
                MiscHeader = BinaryFormat.Binary(14),
                BinarySize = BinaryFormat.ByteOrder(BinaryFormat.UnsignedInteger32, ByteOrder.LittleEndian),
                FileSize   = BinaryFormat.ByteOrder(BinaryFormat.UnsignedInteger32, ByteOrder.LittleEndian),
                FileNameLen= BinaryFormat.ByteOrder(BinaryFormat.UnsignedInteger16, ByteOrder.LittleEndian),
                ExtrasLen  = BinaryFormat.ByteOrder(BinaryFormat.UnsignedInteger16, ByteOrder.LittleEndian)    
            ]),
        
            HeaderChoice = BinaryFormat.Choice(
                BinaryFormat.ByteOrder(BinaryFormat.UnsignedInteger32, ByteOrder.LittleEndian),
                each if _ <> 67324752             // not the IsValid number? then return a dummy formatter
                    then BinaryFormat.Record([IsValid = false, Filename=null, Content=null])
                    else BinaryFormat.Choice(
                            BinaryFormat.Binary(26),      // Header payload - 14+4+4+2+2
                            each BinaryFormat.Record([
                                IsValid  = true,
                                Filename = BinaryFormat.Text(Header(_)[FileNameLen]),
                                Extras   = BinaryFormat.Text(Header(_)[ExtrasLen]),
                                Content  = BinaryFormat.Transform(
                                    BinaryFormat.Binary(Header(_)[BinarySize]),
                                    (x) => try Binary.Buffer(Binary.Decompress(x, Compression.Deflate)) otherwise null
                                )
                                ]),
                                type binary                   // enable streaming
                        )
            ),
        
            ZipFormat = BinaryFormat.List(HeaderChoice, each _[IsValid] = true),
        
            Entries = List.Transform(
                List.RemoveLastN( ZipFormat(ZIPFile), 1),
                (e) => [FileName = e[Filename], Content = e[Content] ]
            )
        in
            Table.FromRecords(Entries),

    SourceWebZipCodes = Web.Contents("https://www.posta.sk/subory/322/psc-obci-a-ulic.zip"),
    Unzipped = Fn_Unzip(SourceWebZipCodes),
    FilteredRows = Table.SelectRows(Unzipped, each ([FileName] = "POBoxy.xlsx")),
    Content = Excel.Workbook(FilteredRows{0}[Content], true),
    ZipCodesTable = Content{[Item="PSČ_POBOXov!_xlnm._FilterDatabase",Kind="DefinedName"]}[Data],
    RenamedColumns1 = Table.RenameColumns(ZipCodesTable,{{"PSČ pre P.O.BOXy", "Zip Code"}}),
    ChangedType = Table.TransformColumnTypes(RenamedColumns1,{{"Zip Code", Int64.Type}}),
    // Table with zip codes I want to transoform to city name.
    SourceZipCodesToDecode = #table(type table[ZIP=Int64.Type], {{96261},{96001},{96233},{90055}}),
    MergedQueries = Table.NestedJoin(SourceZipCodesToDecode, {"ZIP"}, ChangedType, {"Zip Code"}, "ZipCodesWeb", JoinKind.LeftOuter),
    ExpandedZipCodesWeb = Table.ExpandTableColumn(MergedQueries, "ZipCodesWeb", {"Názov pošty"}, {"Názov pošty"}),
    RenamedColumns2 = Table.RenameColumns(ExpandedZipCodesWeb,{{"Názov pošty", "City"}}),
    RemoveSpecialCharsAndNumbers = Table.TransformColumns(RenamedColumns2, {{"City", each Text.FromBinary(Text.ToBinary(Text.Remove(_, {"0".."9"}), 1251), TextEncoding.Ascii), type text}})
in
    RemoveSpecialCharsAndNumbers

Hi @kyliemcpoland 

Yes, you'll need to create a table that contains the zip codes and the corresponding city names.  Then you can create a relationship between that table and your main data table, and write any measures/create visuals you need.
