@J0sh ,

If you use a ReplaceText with the following settings it will clean up the garbage in your flowfiles:

Search Value:      (?s)(^|(\})<br>).*?(\n).*?(<br>(\{)|$)
Replacement Value: $2$3$5

This file, though, has not 1 JSON, but 8 different JSON fragments. So the resulting flowfile will still have 8 lines, each with a valid JSON. You must use a SplitText process to separate those into 8 different flowfiles before applying the EvaluateJSONPath.

Cheers,

André
