# File Convert Common format conversions using Python stdlib + minimal dependencies. ## Quick Conversions ### CSV → JSON ```bash python3 -c "import csv,json,sys; print(json.dumps(list(csv.DictReader(open(sys.argv[1]))),ensure_ascii=False,indent=2))" data.csv ``` ### JSON → CSV ```python import json, csv, sys data = json.load(open(sys.argv[1])) w = csv.DictWriter(sys.stdout, fieldnames=data[0].keys()) w.writeheader(); w.writerows(data) ``` ### YAML → JSON ```bash python3 -c "import yaml,json,sys; print(json.dumps(yaml.safe_load(open(sys.argv[1])),ensure_ascii=False,indent=2))" file.yaml ``` ### JSON → YAML ```bash python3 -c "import yaml,json,sys; print(yaml.dump(json.load(open(sys.argv[1])),allow_unicode=True,default_flow_style=False))" file.json ``` ### Markdown → HTML ```bash pip install markdown python3 -c "import markdown,sys; print(markdown.markdown(open(sys.argv[1]).read(),extensions=['tables','fenced_code']))" file.md ``` ### Base64 encode/decode ```bash base64 < file.bin > file.b64 base64 -d < file.b64 > file.bin ``` ## Universal Converter Script ```bash python3 scripts/convert.py input.csv output.json python3 scripts/convert.py data.yaml data.json python3 scripts/convert.py README.md README.html ``` Auto-detects format from file extension and performs the appropriate conversion.
