Split Column Based on String Text

Hello! I have a column containing trading card series, card number and card name that I want to split, such as:

  • "1989 Comic Images Excalibur 1 Checklist" split into "1989 Comic Images Excalibur" and "1 Checklist
  • "1990 Comic Images Uncanny X-Men II 20 Issue #195"  split into "1990 Comic Images Uncanny X-Men II" and  "20 Issue #195"

 

There isn't consistency in the data to split by Characters or Delimiters, that I have found.

 

Q: Is it possible to specify that if the string contains certain data, to split a certain way? Something like:

IF [Card] contains "1989 Comic" then split....., IF [CARD] contains "1990" then split....

 

I've tried modifying the code after doing one split, but cannot make Power Query happy.

Hi, @beauschoen 

Optimize with M code. For more complex logic that can't be implemented through the UI, consider using the Advanced Editor to manually write or tweak M-code. For example, I create a table

Then use the following M expression

let
CustomFunction = (text as text) as table =>
    let
        splitText = if Text.Contains(text, "1 Checklist") then 
                        Text.Split(text, "1989 Comic Images Excalibur")
                    else if Text.Contains(text, "20 Issue #195") then 
                        Text.Split(text, "1990 Comic Images Uncanny X-Men II")
                    else 
                        {text},
        toTable = Table.FromList(splitText, Splitter.SplitByNothing())
    in
        toTable,
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMrS0sFRwzs/NTFbwzE1MTy1WcK1ITszJTCotUjBUcM5ITc7OySwuUYrVAam1NEBVG5qXnJiXV6kQoeubmqfg6algZKDgWVxcmqqgbGhpqhQbCwA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [column = _t]),
      #"Invoked Custom Function" = Table.AddColumn(Source, "Split", each CustomFunction([column])),
    #"Expanded Split" = Table.ExpandTableColumn(#"Invoked Custom Function", "Split", {"Column1"}, {"Split.Column1"})
in
    #"Expanded Split"

This is just an idea of mine, and you can modify it based on your data
