Excel and Power BI users sometime need to rename multiple columns automatically rather than manually. e.g. auto replacing parts of the names, or using a manual table of "Before and After" to rename your columns.

Hi Wyn, Here's a one step solution that gets straight to the point. In your rename step use this formula: = Table.TransformColumnNames(Source, each Text.AfterDelimiter(_,"_")) and be done with it. 🙂 You're welcome.

Nice video and tips... "shift + 9", I'll only add that the concept behind is: mark the text and "open whatever bracket you need", then you'll have the seleted text with both ( ), { }, [ ].

Hi Wyn, My approach was: Use Headers as first Row, Transpose, Apply transformations needed to column 1 which contains the names of the original columns. Transpose, Use first row was headers

Still getting error. I jave two tables 2022sales, 2023 sales. In first file i have columns carname, year, number of units sold, country. In secnd file i have diffent name number of units as (units) and county as (place) . Ihave created maping tabme exactly and turn it to rows and using in my sample file query. Now the second still shows error not displaying records.a red line across all headers. All date types are checked though

@AccessAnalytic 3 ай бұрын

If you’re running this on a folder of files then you might want to add MissingField.Ignore Something like Table.RenameColumns(_,{{"Product","Item"}}, MissingField.Ignore) This should handle the fact that the columns you’re renaming don’t exist on one file

@danishnawaz3651 6 ай бұрын

Sir, plz make video for below. If 1 table has 9 column, 2 table has 10 and 3 table has 8 . Then how can we make equal all column for all table.. like we want to insert dummy column for missing column in tables and make equal like 10 column for each table.

@AccessAnalytic 6 ай бұрын

That should happen automatically. Tables don’t need the same number of columns

Great video! Related to your “clicks” comment, how much M do you write in your work now? I feel like I’ve reached a place with PQ that that is what I should focus on now, but seldom feel like I have a use case that can’t be solved with the “clicks.”

Sorry it is working now. Just small doubt, could you please let me know whether we can get rid of spreadsheet once we rename the fields so that we dont have any dependency on the spreadsheet

@Mohammad-rz7oj the Power Query code pulls the data from a source and loads it to a destination. If you never to update or refresh the query then yes you can delete the source.

@@AccessAnalytic Thanks for the reply. All these calculations are not working for directquery. What i did instead is wrote a calculation in excel to concatenate old and new column names and updated those in M Lang in Powerquery editor.

How would you handle the error that the field name already exists in the record? I have that error and although I can tell the rename function how to handle missing values there isn't anything tat will say this is what to do when you have an existing name.

@AccessAnalytic 11 ай бұрын

Not sure, maybe some sort of pre check on the renaming table and add a 2 if text already exists if List.Contains( Table.ColumnNames(OriginalTable), [NewName] ) then [NewName] & "2" else [NewName]

You can’t use button clicks on user interface if connection to data isn’t working. Unpivotting is a good technique to avoid referring to columns
