How to debug JSON files

Question

There are several errors in my JSON file. What is the best option for debugging JSON files? I used this editor - http://www.jsoneditoronline.org/, but it's a bit difficult to use for long files.

For instance, the error message says:

Error: Parse error on line 1:
...000.0}]}},"data": [{"id": 0,"fr
-----------------------^
Expecting 'EOF', '}', ',', ']', got ':'"

But the line looks fine.

Try putting your JSON file's content into a validator, like http://jsonlint.com/ or http://jsonformatter.curiousconcept.com/ and see what it says.
