Why teams connect Google Sheets and Microsoft 365

Stop re-entering the same information in Google Sheets and Microsoft 365: Stacksync keeps the records they share consistent in real time, in both directions.

Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.

Stacksync syncs Ranges, Named ranges, Cell values, Spreadsheets in Google Sheets with Contacts, OneDrive Files (driveItems), SharePoint Sites & Lists, Teams in Microsoft 365 in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.

Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.

Common use cases

  • Prototype an integration by syncing a sheet before committing to a database schema.
  • Give ops and finance teams an editable spreadsheet view of CRM or database records, with edits written back to the source.
  • Sync SharePoint lists with operational databases so business users edit in SharePoint while systems read SQL.
  • Archive mail and file metadata into a warehouse for compliance and activity analytics.

Where both tools track people or companies: one consistent record

Contact and company details corrected in either tool update the other, so nobody works from the old version.

Where one tool produces events: mirror them in the other

Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.

Where Microsoft 365 is where the team documents or plans: keep its data fed

Information that originates in Google Sheets stays current in Microsoft 365 instead of going stale after a one-time paste.

What you can sync between Google Sheets and Microsoft 365

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Google Sheets objects Microsoft 365 objects
Spreadsheets The file-level container a sync connects to, identified by spreadsheet ID. SharePoint Sites & Lists List items read and written like lightweight database tables.
Sheets (tabs) Individual worksheets, typically mapped one-to-one to a synced table. Teams Team and membership data provisioned from upstream systems.
Rows Treated as records; a header row usually defines field names. Planner & To Do Tasks Task items synced with project and work-management tools.
Ranges Addressed in A1 notation for batched reads and writes. Users Entra ID user accounts synced with HR and identity systems.
Named ranges Stable references that keep sync mappings valid when the grid moves. Groups Microsoft 365 and security groups kept aligned with org structure and access rules.
Cell values Untyped by default, so syncs handle type coercion for dates and numbers. Mail Messages Exchange Online messages read for logging, archiving, or activity capture.
