Answer 1

Forever old, but I was trying to ingest an AWS CloudCheckr JSON into Excel via Power Query and getting the "We found extra characters at the end of JSON input."
Finally figured out, with the help of https://jsonformatter.org/ that some data was provided as True -- without quotes, which Excel PQ needed. Simple find/replacing :True, with :"True", did the trick.
Seriously, Microsoft, you did not recognize Boolean when you found it? Excel would have had no problem.

Answer 2

The answer is in the error message:
Expecting 'EOF', '}', ',', ']', got '{'
Looking at where { appears notice that directly before that is }. The JSON has no separator after the closing curly } and thus cannot process it because it's looking for one of the following:
EOF
}
,
]
In this case, it most likely needs a ,. It could also need ],, if it's an array of items. If neither of those fix it, you will need to post the entire line 1 of your JSON.

Answer 3

I had to do two changes to make this work: changed json body to Pascal case notation even thought it was in Camel case in chrome payload
, and secondly I was returning a simple string to verify the service is working - once I changed that to an object (as a json formatted response) this resolved the error I was getting.
