It performs automatic type conversion and validation based on dataclass field annotations, catching type mismatches and reporting the exact CSV line where errors occur. The library also provides a writer to serialize dataclass instances back to CSV.\n\nThe package is designed to reduce boilerplate: instead of manually looping through CSV rows, converting strings to the correct types, validating data, and applying defaults, you define a dataclass with type hints and let DataclassReader handle the rest. It supports field mapping for mismatched column names, default values, and datetime formatting via decorators.","worth_installing":"Yes. Zero runtime dependencies, active maintenance, permissive license, and no known vulnerabilities make it a low-risk choice. Install it if you work with CSV files and want type safety and cleaner code than dict-based approaches; skip it only if you need advanced CSV features (e.g., streaming very large files, complex nested structures) beyond the library's scope."},"id":"dataclass-csv","links":{"html":"https://skillfed.io/packages/dataclass-csv","md":"https://skillfed.io/packages/dataclass-csv.md","pypi":"https://pypi.org/project/dataclass-csv/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-02-01","license_spdx":null,"license_treatment":"permissive","name":"dataclass-csv","python_support":"supports_current","summary":"Map CSV data into dataclasses"},"popularity":{"monthly_downloads":133250,"position":11524,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.4.1"}
