Add Text in existing column headers

[PatFr]

Hello guys,

I need your help about the column headers. I just want to add the following word : DARES into all my column headers. I can’t find something to do this. Do you have any idea?

Here is my document

Thanks in advance

Column Rename (regex) is the node. Configured like in the screen shot below.

Found “insert column header” for a type of data source input. Could be helpful for targeted renaming.
