You could use a this function:
Splitter.SplitTextByAnyDelimiter( List.Transform({0..9},each Text.From(_)))(InputText)
bdarbonneau, thank you. Since I am inexperienced with Power Query, I have two questions:
1. How do I use this as a function? Do I just insert the code into the Advanced Editor?
2. Is the line of code you provided complete or do I have to insert anything into Text.From or replace InputText.
Also, does the same code apply for splitting a column with any letter, lowercase or uppercase?
= Table.SplitColumn(#"Changed Type","ColumnA",Splitter.SplitTextByDelimiter(":", QuoteStyle.Csv),{"ColumnA.1", "ColumnA.2"})
= Table.SplitColumn(#"Changed Type","ColumnA",Splitter.SplitTextByAnyDelimiter( List.Transform({0..9},each Text.From(_))),{"ColumnA.1", "ColumnA.2"})
