Automatically generate column caption in power query

[julhelp]

Hi,

i have a question aubout power query. Is there any posibillity to generate automatically the column caption from an table which is retrieved via api from a database? 

So far i have to hardcode it into my last step: 

The problem is, that i want to switch beetwenn other tables and therefore i have to change this step of code by my self. 

this is my code jet:

Have anyone an idea?

Thanks in advance

Not totally clear on your scenario, but you can use Table.ColumnNames() on your [data] column to dynamically generated a list of the column names and use that in place of the hard-coded list.

Since it's a record column, I think you'd use Record.FieldNames instead.

Maybe like this:

[...]
    #"Custom items" = Table.ExpandListColumn(#"Removed Columns", "data"),
    ColumnList = Record.FieldNames(#"Custom items"{0}[data]),
    #"Expanded data" = Table.ExpandRecordColumn(#"Custom items", "data",
        ColumnList, List.Transform(ColumnList, each "data." & _))
in
    #"Expanded data"

hi @AlexisOlson,

Is there also a possibility, if in the output table there are still several columns with records to output them also variably? Or du i have to output them step by step?

You could probably do it but it would likely be more trouble than it's worth unless you have a whole bunch of columns to expand.

The problem is that I would like to apply the code variably to several tables. These do not always have the same headings and therefore cannot be hard-coded.

Yes that was exactly what i was looking for 😉
