Hi @franco69 ,
If I am understanding your question correctly, you're working with Excel sheets where column names change from time to time and you would like your workflow to adapt automatically? Please correct me if I’ve misunderstood!
The functionality you're looking for may be related to dynamic workflows, schema mapping, and/or user parameters. When generating a workspace (Ctrl+G), select 'Dynamic Schema' in the workflow options to add dynamic readers and writers into a basic dynamic workspace to support schema changes. Keep in mind, if you modify attributes mid-workflow (eg. AttributeManager), you may also need a SchemaScanner to retrieve the updated schema before continuing.
Dynamic workflows can get tricky, so I'd recommend starting with the Schema tutorial series. Topics like Schema Drift and SchemaMapper (map varying input attributes to consistent ones) may be especially relevant to your use case. In addition, there are 3 modules in the FME Academy Form Advanced course that also serves as a good general introduction:
Hope this helps point you in the right direction!
