A benchmark test was conducted on seven Python JSON parsers to evaluate their performance on malformed outputs from large language models (LLMs). The test suite, MALFORMED-300, included 300 cases of malformed JSON. The results showed that `json-repair` outperformed the author's tool, `jsonshim`, in recovering data from recoverable cases. However, `jsonshim` was noted for its stricter refusal policy on unrecoverable cases, which is preferable for database entries or tool calls, whereas `json-repair`'s approach of always returning a value might mask errors by turning redactions into valid data.
