CSV - Excel Readers Metadata validation

Sometimes the files we use in our Knime workflows have an unexpected changes in their layout, most common situation is that columns are added to these reports (some excel files have more than 100 columns).
Is there a way to validate that the input files fed into the workflow have exactly the same layout from day before? or the same Layout when the Reader was configured?

This might sound a simple error detection, but my team runs a series of workflows sequentially from a remote call and we would like to validate before executing our workflows batch that all the input files are valid before being used.

Thanks a lot @mlauber71, those two approaches seems to be a good way to solve our issue.
