+// Override the default field name regex. Default: /FieldName: ([^\n]*)/

+This will produce an array of fields like the following.

+[
+    {
+      "fieldFlags": "0",
+      "title" : "first_name",
+      "fieldValue": "",

+      "fieldType": "Button",
+      "fieldDefault": "",
+      "fieldOptions": ["On", "Off"]
+    },
+]
+```
+This can be very helpful when trying to determine what a valid value is to make a checkbox be checked when filling out the PDF.
