Error Handling

I am using an Excel Reader node to read several hundred Excel files. All should have the same structure (i.e., column names), but invariably there is a file that does not conform and I get an error that indicates, “The following columns are not contained in all source files:”. Is there a simple solution to identify the offending file?

@kmarrs901 the concept would work something like this (only a screenshot in the thread):

A sample workflow with a try-catch block that could be modified:

You could record which file failed. Ans also later use that collection to maybe process the failed files again.
