Add headers to CSV file

Tables.PNG

 

Hi all,

 

I have uploaded a CSV file into my PBI project. As the CSV file has no headers, column names in Table1 are shown as Column1, Column2, Column3, ......, Column100.

 

How can I replace those names for the ones that I have defined in Table2.

 

Many thaks for your help

HI @underkar,

 

Based on double check on your snapshot, it seems like your columns are stored in table 2 with original column name and real column name.

 

For your scenario, I modify my formula to use table 2 columns to generate name parameter list which need to be use in table 1.

#"Renamed Columns" = Table.RenameColumns(#"Source",List.Zip({Table2[Column],Table2[Description]}))

HI @underkar,

 

You can use List.zip, Table.Renamecolumns and Table.ColumnNames functions to auto rename one table names based other table.

 

Sample:

 

#"Renamed Columns" = Table.RenameColumns(#"Previous Step",List.Zip({Table.ColumnNames(#"Previous Step"),Table.ColumnNames(Sheet2)}))

Hi @Anonymous, thanks you very much for your reply.

 

I think this code doesn't work in my example, because I don´t need to replace headers in "table1" with headers in "table2", what I need is to lookup Column1, Column2, etc in "table2" and return the text in column "Description" of "Table".

I hope I have explained this better....

 

#"Renamed Columns" = Table.RenameColumns(#"Source",List.Zip({Table.ColumnNames(#"Source"),Table.ColumnNames(Table2)}))

 

Many thanks
