csv-to-json v1.0.0 — First stable release

A lightweight, dependency-free CSV-to-JSON converter for AI agents and developer workflows. Pure Python 3.10+ standard library — nothing to install.

What it does

• Type inference — numeric strings become ints/floats, true/yes & false/no become booleans, empty cells become null (opt out with --no-type-inference)
• Nested key expansion — dot-notation headers like user.address.city expand into nested JSON objects (--expand-keys)
• Streaming — stream_csv_to_json() yields one record at a time, so large files never need to fit in memory
• Flexible input — accepts file paths, raw CSV strings, or stdin; custom delimiters via -d
• Dual interface — use as a CLI (python src/csv_converter.py data.csv -o out.json) or import csv_to_json() as a library
