Adoption guide

Business reporting and spreadsheet workflows where productivity and readable code are primary goals.

Office guide
Why it appears in the guide: Developer-friendly API over Open XML focused on Excel workbook generation and editing. Trade-off: Advanced or niche spreadsheet features may still require direct Open XML workarounds.

This version is marked prerelease. Validate its API and upgrade path before production use.

Compatibility metadata lists 2 target frameworks; confirm the exact target used by your application.
