# powerio-cli
The `powerio` command converts formats, exports matrices and GridFM Parquet
datasets, writes DC OPF bundles, generates synthetic cases, writes `.pio.json`
documents, verifies matrices, and opens a ratatui interface.
Transmission conversion covers MATPOWER, PSS/E, PowerWorld AUX, PSLF, PowerModels
JSON, egret JSON, pandapower JSON, PyPSA CSV folders, GOC3 JSON input, Surge
JSON, and GridFM reads. Distribution conversion covers OpenDSS, PMD JSON, and
BMOPF JSON.
```
powerio convert tests/data/case14.m --to psse -o case14.raw
powerio convert case.surge.json --from surge-json --to matpower -o case.m
powerio convert goc3_case.json --from goc3-json --to matpower -o case.m
powerio package tests/data/case14.m -o case14.pio.json
powerio package goc3_case.json --from goc3-json -o goc3_case.pio.json
powerio verify tests/data/case30.m --kind bdoubleprime
powerio dcopf tests/data/case30.m -o out
powerio sensitivities tests/data/case30.m -o out --solver auto --drop-tolerance 1e-10
powerio
```
`powerio sensitivities --solver iterative` writes Matrix Market coordinates
through temp files, so the command does not keep the full sparse PTDF/LODF
output in memory.
