> We should have a Processor that allows users to easily filter out specific columns from CSV data. For instance, a user would configure two different properties: "Columns of Interest" (a comma-separated list of column indexes) and "Filtering Strategy" (Keep Only These Columns, Remove Only These Columns).
> We can do this today with ReplaceText, but it is far more difficult than it would be with this Processor, as the user has to use Regular Expressions, etc. with ReplaceText.
> Eventually a Custom UI could even be built that allows a user to upload a Sample CSV and choose which columns from there, similar to the way that Excel works when importing CSV by dragging and selecting the desired columns? That would certainly be a larger undertaking and would not need to be done for an initial implementation.
