Pretty Print a simple csv in the command line

python -c 'import sys,csv; c = csv.reader(sys.stdin); [sys.stdout.write("^M".join(map(repr,r))+"\n") for r in c];' <tmp/test.csv | column -s '^M' -t
Will handle pretty much all types of CSV Files. The ^M character is typed on the command line using Ctrl-V Ctrl-M and can be replaced with any character that does not appear inside the CSV. Tips for simpler CSV files: * If newlines are not placed within a csv cell then you can replace `map(repr, r)` with r

  • Splits the input based on commas and prints it in a nice column format. This would not work for CSV rows that have "," between quotes or with newline characters. Use only simple simple csv files. Show Sample Output

    column -s, -t <tmp.csv
