Rename columns names using Java Edit Variable so that every column name is upper case, and all spaces are replaced by underscores. Using Java Edit Variable, the code can be easily be modified to allow you to perform other manipulations across all column names in the data set using a small (but simple) piece of Java. You can of course perform much more specific manipulations by modifying the code slightly to (for example) ignore columns with specific names, or containing specific strings. You could also make it add a prefix or a suffix to all column names.
