Hello,

In my input file called “Account ID” I would like that column to display in my output file. Is there a node for this?

Thanks.

@tyler123 wit a lot of file reader nodes you can directly attach a column containing the (full) path of the file you have just loaded

Then you can store the (selected) file information from your node in a Flow Variable and use that later

For example to extract the ‘pure’ file name and extension. You could also use this to gather other informations.

Then you can store that as a new constant column
