Get first line of the file and positioned values

Hi guys, need help.

 

I need to read a folder that has many text files.

 

From those files, I want only the first line and ignore the other lines.

 

Then I need to get about 20 fields, that are positional, like:

 

column 1 to 3 = client ID

column 4 to 10 = client name

column 11 tp 17 = client state

 

Is that possible?

 

Thanks!

Hi @efilipe ,

 

How about this?

Or, you can refer to this post to get something like below and then transpose your table.

let
    filesInFolder = Folder.Files("D:\Folder Test\"),
    GetFirstRowOfCsv = (someFile as binary) as list => 
        let
            csv = Csv.Document(someFile, [Delimiter=" ", Encoding=65001, QuoteStyle=QuoteStyle.Csv]),
            promoted = Table.PromoteHeaders(csv, [PromoteAllScalars=true]),
            firstRow = Table.ColumnNames(promoted)
        in firstRow,
    firstRowExtracted = Table.AddColumn(filesInFolder, "firstRowExtracted", each GetFirstRowOfCsv([Content]), type list),
    combined = 
        let
            columns = firstRowExtracted[firstRowExtracted],
            headers = List.Transform(firstRowExtracted[Name], each Text.BeforeDelimiter(_, ".txt")),
            toTable = Table.FromColumns(columns, headers)
        in toTable,
    #"Transposed Table" = Table.Transpose(combined)
in
    #"Transposed Table"

I just realized I can split the text after importing. So the problem is getting only ethe first line of each text file.
