I have a lot of JSON-responses that wraps an base64-encoded excelfile (response.json).
If I extract the data-part and try to decode it using BinaryDecoder (base64 to hex I guess). And then decode to ASCII, I get only a few chars that makes no sense.
If I use an online-service (https://www.base64decode.org/) and add the data-part of the JSON-file (JSON response -.....) I get a perfect excel-file.
I can't seem to figure out the part that the online-service performs and the part I can't make FME do.
Any help is appreciated.
