Extract substring from another column in Power Query
Hi, I have a column containing pdf filenames and I want to be able to extract text containing 'BODNNNNNNN' where N represents any single number. Is it possible to create a new custom column in Power Query?
| BOD PDF filename | Expected Output | |
| File1.pdf | ||
| File_BOD1234567_1.pdf | BOD1234567 | |
| BOD7654321_final_1.pdf | BOD7654321 | |
| BOD5555555(22Jan).pdf | BOD5555555 |
Appreciate any advice! Thanks!
In a custom column, use following
= [s=Text.Middle([BOD PDF filename],Text.PositionOf([BOD PDF filename],"BOD"),10), r = try if Value.Is(Number.From(Text.End(s,7)), type number) then s else null otherwise null][r]See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcsvMSTXUK0hJU4rVgfDinfxdDI2MTUzNzOMRMkBBczNTE2Mjw/i0zLzEHFQpUwjQMDLySszTRJZRio0FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"BOD PDF filename" = _t]), #"Added Custom" = Table.AddColumn(Source, "Custom", each [s=Text.Middle([BOD PDF filename],Text.PositionOf([BOD PDF filename],"BOD"),10), r = try if Value.Is(Number.From(Text.End(s,7)), type number) then s else null otherwise null][r]) in #"Added Custom"
