 ### Output column type
 
-Here is where you'll configure the target output schema from the parsing that will be written into a single column. The easiest way to set a schema for your output from parsing is to click the 'Detect Type' button on the top right of the expression builder. ADF will attempt to autodetect the schema from the string field which you are parsing and set it for you in the output expression.
