Why teams connect Google Cloud Platform and Microsoft 365

Get the data locked inside Microsoft 365 into Google Cloud Platform as live tables, and send results back where Microsoft 365 can use them, without writing a pipeline.

Whatever Microsoft 365 is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Planner & To Do Tasks, Users, Groups, Mail Messages from Microsoft 365 into tables in Google Cloud Platform continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Google Cloud Platform can also be written back into fields in Microsoft 365 where the tool can use them.

Common use cases

  • 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.
  • Publish change events to Pub/Sub so downstream services react to record updates as they happen.

Analytics on Microsoft 365's data

Records and events from Microsoft 365 land in Google Cloud Platform as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine Microsoft 365's data with data from every other synced system to answer questions no single tool can.

Where Microsoft 365 accepts updates: operational write-back

Segments, scores, or reference values computed in Google Cloud Platform sync back onto records in Microsoft 365, putting analysis where the work happens.

What you can sync between Google Cloud Platform 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 Cloud Platform objects Microsoft 365 objects
BigQuery tables The primary analytics destination, written through load jobs or the Storage Write API and queried with SQL. Mail Messages Exchange Online messages read for logging, archiving, or activity capture.
Cloud SQL databases Managed Postgres, MySQL, and SQL Server instances synced like ordinary relational databases. Calendar Events Events synced with scheduling tools and CRMs for meeting visibility.
Cloud Storage objects Staging area for file-based bulk loads into BigQuery and other services. Contacts Personal and org contacts kept consistent with CRM contact records.
Pub/Sub topics Event streams used to move change events between systems in near real time. OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits.
Firestore documents Document data read and written through the Firestore API for app-facing syncs. SharePoint Sites & Lists List items read and written like lightweight database tables.
Spanner tables Strongly consistent relational tables accessed via SQL for transactional workloads. Teams Team and membership data provisioned from upstream systems.
