CSVX Web is the React/Vite demo workbench for opening, inspecting, editing, and exporting CSVX files. It is a consumer of the CSVX specification and engine model, not a second definition of the format.
The first slice is an accessible, developer-oriented workbench with local editing capabilities:
- Workbook and sheet navigation
- CSV-backed spreadsheet data display
- Cell selection with A1 coordinates
- Package and data-layer context
- Responsive layout and keyboard-visible focus states
- Cell editing with Enter, Space, F2, and Escape to cancel
- Row context menu actions for insert-before, insert-after, and delete
- LocalStorage persistence for edits during the demo session
The current demo data is represented in the UI while the browser-side CSVX package reader is being
added. example.csvx is the real CSVX package fixture for that integration.
npm install
npm run dev
npm run build
npm run preview
# Development server uses port 5174
npm run dev./bin/csvx convert ../csvx-web/example.xlsx ../csvx-web/example.csvx The UI will remain separate from CSVX semantics. The browser application should eventually load the
ZIP package client-side, preserve CSV and .meta.json resources, expose formulas and diagnostics,
and export a valid .csvx package without requiring an upload to a server.
