## AI interpretation — verify before relying

ijson is an iterative JSON parser that processes JSON streams using standard Python iterator interfaces, enabling memory-efficient parsing of large JSON documents without loading them entirely into memory.

Verdict: ijson is a production-stable, actively maintained streaming JSON parser suitable for processing large JSON files efficiently. Zero vulnerabilities, permissive dual licensing, and broad Python version support (3.9–3.14) make it a low-risk choice. Medium install friction is offset by prebuilt wheels across major platforms and no runtime dependencies.
