csvfilter 0.2.2

A command-line utility and Python API for manipulating CSV data, eg plucking columns and reordering them. It's a bit like the unix utility 'cut'

Install

From PyPi:

pip install csvfilter

Use

Pluck fields 1, 3 and 5 from in.csv:

csvfilter -f 1,3,5 in.csv > out.csv

Pluck all fields apart from column 2 from STDIN:

cat in.csv | csvfilter -f 2 -i > out.csv

Convert pipe-separated file to comma-separated (default-separated output is comma-separated):

csvfilter -d"|" in.psv > out.csv

Skip the header row:

cat in.csv | csvfilter --skip=1

As you can see, CSV data can be supplied through STDIN or by running csvfilter directly on a file.

Help is in the usual place:

$ csvfilter --help
