Hello,

I am looking for a way of creating and executing a flow based on an input file. I am currently looking at the json format however I do not have any hard constraint related to that.

Specific dummy usecase:  
Input:  
books.csv  
authors.xlsx  
rules.json

the rules.json would contain the details on how to load the data from bought files, how to aggregate them, and also how to create an output file with the aggregated data. This rules.json would be read, parsed and translated into other knime rules.

Would something like this be possible?

Hello @wyking ,  
Welcome to the KNIME Community!

I think that should be possible, but I haven’t worked on such use cases. For starters, I recommend reading the data using the CSV reader, Excel reader, and JSON reader nodes and then continuing with the workflow.

Thanks,  
Sanket
