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.
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"
