solana-keypair-export

This package does exactly one thing: it reads a Solana keypair JSON file and spits out a base58-encoded private key string you can paste into Phantom wallet's import flow.

That’s it. No CLI flags. No validation. If you give it garbage, it gives you garbage back.

I built it because I couldn’t find one, didn’t feel like overthinking it, and wanted to be able to grab it from whatever machine I was stuck on. Now it’s floating around the internet, and somehow it’s your problem too.

Install

npm install solana-keypair-export

Usage

const getPrivateKey = require('solana-keypair-export');

const privateKey = getPrivateKey('./path/to/your/keypair.json');
console.log(privateKey);

That’s it. It reads the file, converts the bytes, and gives you a base58 string you can paste straight into Phantom wallet’s import screen. If it breaks, well, maybe don’t give it garbage input.
