In M Query, my dataset contains a column holding file names.
The file name can have any number of words in it, but the last words are always the month and year. The month however can be truncated, or full e.g. Jan or January
So, I want to split the column by delimiter, from the right, but I want to ignore the first space. Which in theory, means I should have the month and year irrespective of the number of characters, in a new column and rest of the file name in the other.
I can't find a way to do this.
Solved! Go to Solution.
Hi @Anonymous ,
Try this:
1. Duplicate column.
2. Extracted Text Before Delimiter.
3. Extracted Text After Delimiter.
Then, change column names.
Attach the complete code.
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcsvMSTVUMDIwtFTwSsxTitWBCBlBhNxSk+BCxhAh38Si5Ay4oIlCcXExRMIlNTk1Nym1SCk2FgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
#"Duplicated Column" = Table.DuplicateColumn(#"Changed Type", "Column1", "Column1 - Copy"),
#"Duplicated Column1" = Table.DuplicateColumn(#"Duplicated Column", "Column1 - Copy", "Column1 - Copy - Copy"),
#"Extracted Text Before Delimiter" = Table.TransformColumns(#"Duplicated Column1", {{"Column1 - Copy", each Text.BeforeDelimiter(_, " ", {1, RelativePosition.FromEnd}), type text}}),
#"Extracted Text After Delimiter" = Table.TransformColumns(#"Extracted Text Before Delimiter", {{"Column1 - Copy - Copy", each Text.AfterDelimiter(_, " ", {1, RelativePosition.FromEnd}), type text}}),
#"Renamed Columns" = Table.RenameColumns(#"Extracted Text After Delimiter",{{"Column1 - Copy", "File"}, {"Column1 - Copy - Copy", "Year Month"}})
in
#"Renamed Columns"

Hi @Anonymous ,
Try this:
1. Add Column → Column From Examples.
2. Enter sample value.
3. Modify the value that does not match.
4. OK.

Thanks Icy,
But I was really hoping not to have to add a column but to split the column because I also need the text before the date as well - as that is the Vendor name.
Also, I tried your method but poor Power BI couldn't figure out that the last part of the text string was a date.
I am able to extract the date using 'Add Column' > Split by delimeter which successfully extracts just the date by using the below code, but I am still left with the original column [Claims Vendor] where I need to do all sorts of crap to get the entire name, because again, it's either a single word, or two words.
If I could perform the below with a transform.column instead of a add.column it would be perfect but it doesn't allow it!!
= Table.AddColumn(PreviousStep, "Invoice Period", each Text.AfterDelimiter([Claims Vendor], " ", {1, RelativePosition.FromEnd}), type date)
