WorkbookLens v2.3.0

WorkbookLens 2.3.0 introduces a native Windows desktop experience, consistent Chinese and English operation, and more reliable local legacy Excel conversion and upgrades.

Highlights

• Adds a native Windows desktop interface powered by WebView2, so normal launches stay inside a WorkbookLens application window instead of opening the default browser or displaying a console window.
• Adds a Chinese and English language selector. Navigation, forms, results, and recoverable user-facing errors follow the selected language.
• Strengthens local conversion of trusted legacy .xls workbooks to .xlsx, including safer Excel executable discovery, clean PowerShell error decoding, bounded timeouts, converter fallback, and owned-process cleanup without terminating existing user Excel processes.
• Updates both portable ZIP and Windows installer builds with improved startup and cleanup validation, in-place upgrade handling, refreshed shortcuts, Installed apps registration, and uninstall support.
• Keeps workbook processing local on the user's computer; uploading files to an external service is not required.
• Validated by 636 automated tests with 80.35% coverage and successful GitHub release-candidate workflow run 32611847440.

Security Notes

The Windows binaries are currently unsigned and this release does not include build provenance or an attestation. Windows SmartScreen may display a warning. Verify downloads with SHA256SUMS or the included sidecar checksum files. Only convert .xls files from trusted sources because local spreadsheet applications may process workbook-defined behavior.
