I’m finishing my project where I merge GDP, GDP per capita, GDP PPP and GDP PPP per capita data with Gini coefficient. Workflow is almost done, however I realised that historical records referring to above-mentioned data from years range 1960-1989 are mostly incomplete.
Could you advice how I may wipe out columns only using a column name a reference?
There is any loop possible, because Reference Column Filter is not offering such feature.
In the attachment section I’m pasting my workflow and required data.
Thank you in advance!

If I am understanding correctly, then I would approach this by passing the column names via flow variable into the column filter node.
I will test it today.
By my mind it looks like solution.
A shorter way of doing would be to just Regex Select the required range through a Column Filter via
I am on my cell today so I can’t see the data structure, but if the column names are indeed that simple / uniform then I would definitely go with the Regex select myself.
