Simply follow the instructions here. Write out the content (or if you already have the content to hand, copy and paste it) into the left field. This is where your normal text goes. You will then see in the right field, that’s where the text gets transformed into the italics version.
Once you’ve done this, you can simply head over to the right-hand column, select it all and then copy it and you will then be able to paste it wherever you desire.
If you are looking for an example of italic text then please see below:

If you have any further suggestions on improving the italic text tool further, please also get in touch, as we would love to hear any ideas you might have.
