Sometimes, you may have to change the case of some text to lower case. This can be useful if you want to append this text to some other text.

The data contained in the two renamed columns starts with an upper case. You will put the all the text in lower case, in order to merge the two columns.


  1. Select the column containing text you want to change to lower case, email_first_name in this example.
  2. In the functions panel, type Change style to lower case and click the result to execute the associated function.

    You have the possibility to output the result of this function in a new column by selecting the Create new column check box.

  3. Repeat these steps to put the email_last_name column in lower case.


The text contained in the two columns is now in lower case.
