There are always many, but in comparison to csv I've received almost no differences. Json issues were rare but csv issues it was common to have a brand new issue per client. Typically the big difference is there are different parsers that are less tolerant of in spec values. Clickhouse had a more restrictive parser, and recently I've dealt with matrix. Maybe I've been lucky for json and unlucky for csv.
