remove duplicate headers after combining multiple files

Hi all,

 

I have several csv files to be combined together into a single file for editing and analysis. Each csv file has some headers and these headers are the same. As you can imagine, these headers will be included in the file. How do I remove these redundant headers in the Query Editor? The Remove Duplicates will do the job but I feel that it would remove duplicate data as well.

 

Thanks

As the column names are known, you can remove the header rows with Table.RemoveMatchingRows.

Check

 

let
    Source = Table.FromRows({{"data1","data2","data3"},{"column1","column2","column3"},{"data1","data2","data3"}},{"column1","column2","column3"}),
    RemoveHeaders = Table.RemoveMatchingRows(Source,{[column1= "column1",column2= "column2",column3= "column3"]})
in
    RemoveHeaders
