This Excel guide explains how to integrate Cloud Storage with Embedded Excel Using WOPI.

1. Review Microsoft's Cloud Storage Partner Program and WOPI requirements and register the storage host with the required discovery actions.
2. Implement CheckFileInfo and the file read/write endpoints with user-scoped authorization for the embedded Excel file.
3. Launch Excel for the web with a short-lived WOPI access token and a source URL that the Office service can reach.
4. Run WOPI validation and test open, edit, save, lock, and conflict behavior with a minimal XLSX before production.
