Field Replacer Processor
In this article
A field replacer allows you to replace a field value by providing a hard coded value e.g. null with “some value”, replace a value which is following a pattern by providing regex, and replace a field value by other field value or combination of field values.
You can replace input field if the regex pattern matches.
There are two option to provide values.
- Value will be a combination (concatenation) of two columns. - Example: “JOBROLE” CONCAT “NAME”. - Order in which you select the columns will be considered for the combination. 
- Enter a single value to replace with.
