Data handling

Where your workbook data goes.

A factual account of what stays on your machine and what is sent to Mac-Cel Cloud. No trust badges — just the data-handling map.

Mac-Cel does not upload your workbook to our servers for formula or risk analysis.

Stays on your machine

  • Formula parsing and evaluation
  • Risk detection
  • Sheet dependency mapping
  • Object inventory
  • Deck scanning — performed in the Office client and, when deeper file inspection is needed, by a local helper on your own machine

Sent to Mac-Cel Cloud

  • Account credentials and session tokens
  • Organization, user, and license metadata
  • Firm brand profiles and logo assets
  • Shared library items and thumbnails

Microsoft Graph

When Excel→PowerPoint linking is configured against a workbook saved to OneDrive or SharePoint, PowerPoint reads that saved workbook through Microsoft Graph to refresh linked pictures.
