Splitting cell values in a column to different rows

Use Case

You need to split cell values in a column for further rows data aggregation.

Solution

1. Switch the page to the edit mode.
2. Insert the Table Transformer macro and paste the table or the macros outputting tables within the macro body.
3. Select the macro and click Edit.
4. In the Presets tab select Custom transformation and click Next.

5. Enter the following SQL query:

   SEARCH / AS @a EX('Skills'->split(",")) / 
           RETURN(@a->'Name' AS 'Name', _ AS 'Skills') FROM T1

   CODE
6. Click Next. 
7. Define the table settings and view options if needed. 

8. Save the macro and the page.
   
   

In this case the underscore in the query (i.e.  _ AS 'Skills') is utilized as a beacon to return the transformed data in the Skills column, while @a -> returns the data corresponding to their row values, hence multiplying them as the Skills column data obtain additional rows after being split. 

The resulting table can be further utilized with the Pivot Table macro for distinct value aggregation, counting and so on.
