Flow Variable limit for excel writer?

Hello KNIME folks,

i have a workflow in which I build the outputfile location via flow variables.
This is needed, as I have a loop and therefore need to change the names of the files I want to save.

i use a “merge variable”, “string manipulation” and “create file name” node to create the variable that i then hand over to the excel writer node.
So far this all works, but when i want to select the variable in the excel writer it is not there:

output of the “create file name” node:

available flow variables in the excel writer:
(there are 2 more below but not the one i need)

many thanks for your help

I suggest to use a variable to table node between string manip and create file name


@adaptagis thanks a lot, works !
