It would be nice to have in the Talend suite (like other ETL / ESB tools already do on the market ie Adeptia does something of this sort) a friendly portal to let users to manually upload a file, handling any exception and non conformance, applying a pre made preparation, and then passing the file to invoke some ETL process downstream built with Talend if all is good and fine (usually not with excel files ))
Is there something like that planned in the Data Fabric enterprise version?
Absolutely. Our commercial add-on in June will be fully integrated with the rest of the Talend Data Fabric. Also as a Studio user you will be able to integrate a Data Prep "recipe" into a job (I have already demonstrated this on a pre-version in a webinar; scroll down in the product page). Later this year we will leverage our Spark generation to run your preparations on big data too.
