OpenVariant is a comprehensive Python package that provides different functionalities to read, parse and operate different multiple input file formats (e. g. tsv, csv, vcf, maf, bed), being able to customize the output.

Its aim is being able to manage a ton of data represented in multiple ways and be able to build an unified output with a proper annotation file structure. This package was thought to work with any kind of data that can be represented as a table.
