How to Rename Column Headings with Power Query - the quick automated way

Тәжірибелік нұсқаулар және стиль

⏬ Click Show More to check out the description for info and links⏬
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.
I explain 2 methods List.Zip and the simpler Table.ToRows

    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, 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.

    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

    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.
