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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
