I have troubles figuring out using a loop. I have a folder with 20+ files, all with the same structure, and the same titel-structure. My goal is to concatenate all these files, but first include parts of the title as seperate columns. So I need to read file1, add columns with values from the title, read file2, add columns, concatenate the files etc.
just to add info that there are reader nodes that don’t require loop as they have option to read multiple files from same folder. But to see if it could be used in your case check @Gavin_Attard question
