csv-to-json v1.0.0

A lightweight, zero-dependency CSV-to-JSON converter built on Python's standard library.

Features

• Type inference — automatically casts CSV values to int, float, bool, or null
• Nested key expansion — dot-notation headers (e.g. user.name) become nested JSON objects
• Streaming mode — process large CSV files row-by-row without loading into memory
• Flexible input — accepts file paths, raw CSV strings, or stdin
• CLI + library — use standalone from the command line or import as a Python module

CLI Usage

python src/csv_converter.py data.csv -o output.json
python src/csv_converter.py records.tsv -d '\t' --expand-keys --compact
cat data.csv | python src/csv_converter.py -

Requirements

• Python 3.10+
