Table.SelectRows wildcards
- Anonymous4 years ago
Hi Anonymous ,
To my knowledge, wildcards to directly filter rows is not available in Power Query.
But an idea similar with what you expect has been submitted in the following link, please vote it up and you can add comments in it: Search or Filter with a Wildcard
As a workaround, you could use Text.Length() ,Text.StartsWith() , Text.EndsWith(), Text.Range() to get the expected:
1.Add a custom column
2.Then select rows when Custom=1
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSsvMSY03MjAy1DUAIb2SihKlWB10cSMc4sY4xE0wxfUNjPSR1CcmJSOUm8KFU1LTwMIwlbEA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}), #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each if Text.Length([Column1])=19 and Text.StartsWith([Column1],"file_") and Text.EndsWith([Column1],".txt") and Text.Range([Column1],9,1)="-" and Text.Range([Column1],12,1)="-" then 1 else 0), #"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([Custom] = 1)) in #"Filtered Rows"Best Regards,

smpa01 ronrsnfld Anonymous thanks, RegEx would be great! How can I use them?
An example of what I want to catch is:
file_2021-01-01.txt
file_2021-01-02.txt
file_2021-01-03.txt
file_2021-01-04.txt
I am looking something like: file_????-??-??.txt or even better file_\d\d\d\d-\d\d-\d\d.txt
You've been asked before for "an example dataset and desired end result." Is there some reason you are not supplying this? It would make helping you much simpler.
