Advanced: Transform sections data

The following example shows using computed fields to transform sections data. The example:

• Adds a policy number and name to each section using the Copy To Section method. The policy number and name are listed once in the document and are globally applicable to every extracted claim. The example shows how to transform copied data, in this case by concatenating the copied fields.
• Redacts a telephone number. The example uses the Custom Computation method to replace digits in the number, and the Suppress Output method to omit the complete number from the output.
