still

still is a program for validating tabular data from CSV, TSV, and Excel.

Quick Start

Generate a schema. Directives start with @ and refer to global options. These are followed by column names and test expressions.

cars.schema

@separater TAB
mpg: is_numeric()
cyl: range(2,8)
hp: is_positive() && range(10, 500)
vs: is(0) || is(1)
am: any(0, 1)

Then run the command line tool:

still validate cars.schema cars.tsv

still is largely influenced by csv-validate, but offers more flexibility when validating tabular data. Major differences include:

still allows you to specify column indexes by their name, meaning columns can be in any order.
still can read Excel files
