Koffing is a Pokemon Showdown Team parser that converts your strategies to machine-readable JSON code.

koffing 🔁koffing

Pokémon Showdown is the most popular online Pokémon battle simulator, one of the best ways to quickly try your strategies for the official Pokémon VGC Championships. This library is just a parser for the teams generated by the Showdown Team Builder exports.

This repository holds the source code for the library as well as the code for the Online Parser. The Online Parser, does not require you to download any library or script, it is recommended if all you want is to sanitize, prettify or convert to JSON your Showdown team exports.


  • Compatible with web browsers and NodeJS, including ES6+ imports
  • Converts from Showdown code to JSON
  • Converts from JSON to Showdown code
  • Sanitizes Showdown code (removing invalid data, applying max and mins values, etc.)
  • Prettifies Showdown code (proper indentation, line breaks and sorting of the data, etc.)
  • Online Parser, which is using the library featuring all the above mentioned.


As a package:

npm i --save koffing

<script src="https://cdn.rawgit.com/capsulemonsters/koffing/0.4.0/dist/koffing.min.js"></script>

  • parse(): PokemonTeamSet: Parses the Showdown code and returns a PokemonTeamSet object.
  • format(): String: Parses the Showdown code and returns a prettified and sanitized version of it.
  • toString(): String: Basically returns the internal Showdown code string as it is.

Koffing class methods:

  • static parse(showdownCode): PokemonTeamSet: Wrapper for ShowdownParser.prototype.parse()
  • static format(showdownCode): String: Wrapper for ShowdownParser.prototype.format()
  • static toJson(showdownCode): String: Wrapper for ShowdownParser.prototype.parse().toJson()
