This code is a local file normalization/conversion utility that reads input files and writes Markdown/CSV outputs. It does not show direct malicious behavior like network exfiltration, keylogging, or obfuscated payloads. However, it can execute external commands via `subprocess.run`—either a host-discovered `markitdown` binary or arbitrary commands specified in `parsers/registry.json`—which creates a significant supply-chain/sabotage risk if those files/binaries are compromised or attacker-controlled.
