NFO File Converter

This tool converts metadata text files such as NFO and DIZ between formats and encodings. It accepts single files or zipped archives, detects encoding, and outputs in targeted formats like plain text, JSON, or XML. Under the hood, it uses deterministic text normalization, line ending handling, and punctuation-preserving mapping to maintain data fidelity. Typical users include software archivists, game archivists, developers documenting release notes, and QA teams who need consistent metadata across systems. The core value lies in eliminating manual reformatting, enabling batch processing, and preserving content integrity when moving between legacy and modern pipelines. Advanced options provide encoding detection, line-ending normalization, and optional metadata extraction to structured schemas. The tool enforces strict validation on input mime types, enforces size limits, and returns a downloadable artifact with a clear filename and optional companion log. It can be integrated into pipelines via API or CLI, enabling automated processing in CI/CD or archival workflows. Use cases include converting NFOs to plain text for publishing, transforming DIZ captions into structured elements for catalogs, and generating lightweight JSON for ingestion into search indices. Distinctive value comes from robust error handling, support for non-ASCII characters, and preserving original content structure where possible. Outputs include plain text, JSON, and XML representations, plus optional metadata blocks. This makes it suitable for software libraries, game archives, and digital libraries that require consistent metadata handling across formats.
