+
+.. 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
