## What it is
PKHeX is a Pokémon core series save file editor written in C# using Windows Forms. It can edit, validate, and convert save files, individual Pokémon entity files, Mystery Gift data, and transfer Pokémon between game generations.

## Use cases
- edit pokemon save files from any core series game
- convert pokemon between different game generation formats
- check whether a pokemon is legal for online battles and trades
- import pokemon showdown sets or qr codes into a save file
- extract and convert mystery gift files into pokemon entities
- transfer pokemon from pokemon go via go park entities
- backup and manage decrypted save data from consoles

## When to choose
- you need to edit or inspect decrypted pokemon save files from gen 1 through the latest games
- you want to validate pokemon legality or convert formats between generations
- you need a class library for programmatic pokemon save manipulation in .NET

## When to avoid
- you need a native macOS or Linux application - it is Windows Forms only and requires virtualization elsewhere
- you want to edit encrypted console saves directly - saves must first be decrypted with a savedata manager like Checkpoint or JKSM
- you are looking for a tool to cheat in online battles, which the project explicitly does not condone
