M365 Tenant Reporter supports four export formats because one tenant snapshot often serves multiple audiences. The right format depends on whether the next step is human review, system ingestion, or portable evidence.

When to use each format

• Use Excel for analyst-friendly review and workbook sharing.
• Use CSV when another reporting tool expects a flat table.
• Use JSON when you want a machine-readable structure for custom processing.
• Use HTML when you need a portable browser-ready artifact.

Why this fits the zero-storage model

The file is generated in the browser, offered to the user immediately, and not retained as a server-side artifact by the application.
