**This tool breaks column assignments.** To re-establish column assignments run the tool and click on the pencil icon in the resulting history item.

.. class:: warningmark

The format of the resulting dataset from this tool is always tabular.

-----

**What it does**

This tool selects specified columns from a dataset and converts the values of those columns to upper or lower case.

- Columns are specified as **c1**, **c2**, and so on.
- Columns can be specified in any order (e.g., **c2,c1,c6**)

-----

**Example**

Changing columns 1 and 3 ( delimited by Comma ) to upper case in::

  apple,is,good
  windows,is,bad

will result in::

  APPLE is GOOD
  WINDOWS is BAD
