Adding column from another Excel source

Hi all,

Salesmen of the company need to fill in a Excel list for each event they make, so we have multiple Excel files. Here the "problem" I'm having, I would like to "merge" all those files in one but in this case I would like to only add the column with results.

 

Files are something like following:

File 1

Q A1
Q B2

File 2

Q A3
Q B4

 

Merged File should be something like following

Q A13
Q B24

 

Is something like this possible?

Cheers

Hi @KelvinMorel, if you want to make it dynamic - you can do it this way:

 

Lets assume you have such files in same folder, they looks like this and you have questions and answers stored in Sheet1 in each file:

 

File1

dufoq3_1-1715001251081.png

 

File2

dufoq3_2-1715001284351.png

 

Result

dufoq3_0-1715001219333.png

 

Change folder addres in Source step:

let
    Source = Folder.Files("c:\Downloads\PowerQueryForum\KelvinMorel\"),
    FilteredExcelFiles = Table.SelectRows(Source, each Text.StartsWith([Extension], ".xls")),
    BinaryToTable = Table.TransformColumns(FilteredExcelFiles, {{"Content", each Excel.Workbook(_, true){[Name = "Sheet1"]}[Data], type table}}),
    CombinedTables = Table.Combine(BinaryToTable[Content]),
    GroupedRows = Table.Group(CombinedTables, {"Questions"}, {{"All", each 
        [ a = Table.RemoveColumns(Table.FirstN(_, 1), {"Answers"}),
          b = List.Accumulate({0..List.Count([Answers]) -1}, a, (s,c)=> Table.AddColumn(s, "Answer" & Text.From(c+1), (x)=> [Answers]{c}, type text))
        ][b], type table}}),
    CombinedAll = Table.Combine(GroupedRows[All])
in
    CombinedAll

in excel we can do this with the help of vlookup from the another workbook  and in power query we can merge both files and expand only answers columnsScreenshot (32).png
