->1.1. Make sure you have already split the author names into individual cells using ```Edit cells->Split multi-valued cells``` (you should have done this in the Clustering lesson)
->1.2. On the Authors column, use the dropdown menu and select ```Facet->Custom text facet...```
->1.3. The ```Custom text``` facet function allows you to write GREL functions to create a facet
->1.4. In the Expression box type ```value.contains(",")```
->1.5. Click ```OK```
->1.6. Since the ```contains``` function outputs a Boolean value, you should see a facet that contains 'false' and 'true'. These represent the outcome of the expression, i.e. true = values containing a comma; false = values not containing a comma
->1.7. In this facet select 'true' to narrow down to the author names that contain a comma
->
->Now we have narrowed down to the lines with a comma in a name, we can use the GREL ```split``` function. This is different to the ```Split multi-valued cells``` operation we have previously used as it allows us to manipulate the content of a cell, rather than create new cells.
->
->2.1. On the ```Authors``` column use the dropdown menu and select ```Edit cells->Transform ```
->2.2. In the Expression box type ```value.split(", ")``` (make sure to include a space after the comma inside the split expression to avoid extra spaces in your author name later).
->2.3. See how this creates an array with two members in each row in the Preview column
->
->To get the author name in personal name first order you can reverse the array and join it back together with a space to create the string you need:
->
->3.1. In the Expression box, add to the existing expression until it reads ```value.split(", ").reverse().join(" ")```
