    Hi AshleyWells 

     

    Please add a custom column with this. Notice that there is a pair of {} around [ColumnData]. 

    = Table.AddColumn(PreviousStep, "Custom", each #table([ColumnNames],{[ColumnData]}))

    Then expand the custom table column.

Hi AshleyWells,

 

Could you share an image of the contents of the [ColumnData]  column as well?

 

I've assumed it contained either a list with nested lists (one for each column header) in that case the list count for [ColumnData] and [ColumnHeaders] should be equal. OR it contained a list with nested lists (one for each row in the table) BUT it could also contain a list with nested records...

 

Can you drill down intoit and let met know what you find?

Thanks!

Hi m_dekorte 

 

I have to be carefull with this data as it's sensitive

Both [ColumnData] and [ColumnNames] should hold the same amount of data in each list.

In the bottom 2 rows of the [ColumnData] there is nested data but I don't need this extracting.

 

Thanks so much for your help so far

 

Ash
