Flat file data munger

This is an experiment

Sometimes awk, grep, and sed aren't available. For those times, flt is a simple tool for manipulating and reshaping flat files commonly used by data analysts and data scientists.

Examples

Take a specific set of rows

flt input.csv --skip 3 --nrows 100

Take a specific set of columns

flt input.csv --columns "ID,GEONAME,POPULATION"

Filter by a predicate

flt input.csv --predicate "GEONAME='British Columbia'"

Convert formats

flt input.csv --format json

flt input.csv --format libsvm --libsvm-label "AMBULANCE_CALLS"
