DFT Analyzer

Offline desktop app (Electron + React) for importing DFT Excel exports (daily or monthly) and viewing them as charts against spec limits.

Stack

• Electron (offline shell, native file dialogs)
• React + Vite
• Tailwind CSS v4
• SheetJS (xlsx) for parsing
• Recharts for charts
• Zustand for state

Project layout

electron/         Main process (window, file-open dialog) + preload bridge
src/parsing/       Excel -> normalized record parsers (daily/monthly layouts)
src/aggregation/   Stats: avg/std/range vs LSL/USL, spec-flagging
src/components/    UI: upload panel, view toggle, filters, charts, tables
src/state/         Zustand store

Getting started

npm install
npm run electron:dev   # runs Vite + Electron together, with hot reload

Build a distributable

npm run electron:build

Output goes to release/.

Status

Setup verified: Electron's native file-open dialog reads Excel file bytes via IPC and hands them to the React renderer (see src/App.jsx). Parsing, aggregation, and dashboard UI are the next pass.
