Fault-Level Workbook (openpyxl)

Upload a fault-results JSON (one entry per bus with currents per fault type) and a breaker rating, get a multi-sheet styled XLSX — one tab per fault type plus a Summary tab with formulas. Conditional formatting highlights any fault current that exceeds the breaker rating.

Try sample

fault-results.json *Array of objects with keys: bus, voltage_kV, '3-phase', 'L-G', 'L-L', 'L-L-G' (kA each).

drop or click — accepts .json

Breaker rating (kA)
