Offray I have a workaround, not an explanation. I don't use NeoJSON, because for me the JSON facilities of STON are sufficient. So I tried you script with 'NeoJSONReader fromString:' replaced by 'STON fromString:' - everything worked perfectly, no parsing error. So clearly there is nothing wrong with your input file. If you have STON installed, or think it worth installing, this could get you moving.

Hi, I'm trying to read the contents of a Wikipedia article that was exported from there using Wikipedias JSON API. The script I'm trying is: NeoJSONReader fromString: 'https://mutabit.com/repos.fossil/pharopedia/doc/tip/docs/wikipedia.org/wiki/en/Pharo/contents.json' asUrl retrieveContents utf8Decoded But I get "NeoJSONParseError: invalid input: '". As far as I can tell, the file at [1] seems like valid JSON, as is the one that Wikipedia API exports [1] 'https://mutabit.com/repos.fossil/pharopedia/doc/tip/docs/wikipedia.org/wiki/en/Pharo/contents.json' Could anybody point me to a solution? Thanks, Offray
