powerio

powerio parses power system case files into a typed Network. Readers retain source text where supported, so writing back to the same format can return the original bytes. Cross format conversion passes through the format neutral network model and reports fields the target cannot represent.

Read and write support covers MATPOWER, PSS/E, PowerWorld AUX, PSLF, PowerModels JSON, egret JSON, pandapower JSON, PyPSA CSV folders, and Surge JSON. GOC3 JSON and PowerWorld PWB are read only inputs.

use powerio::{TargetFormat, parse_file};

let parsed = parse_file("case14.m", None)?;
let net = parsed.network;
let converted = net.to_format(TargetFormat::PowerModelsJson)?;
std::fs::write("case14.json", converted.text)?;

The workspace README lists the CLI, language bindings, matrix builders, and validation commands.
