Why teams connect BigQuery and Microsoft 365

Get the data locked inside Microsoft 365 into BigQuery 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 OneDrive Files (driveItems), SharePoint Sites & Lists, Teams, Planner & To Do Tasks from Microsoft 365 into tables in BigQuery continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in BigQuery 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.
  • Maintain a customer master table in BigQuery joined across CRM, billing, and support sources
  • Feed ML feature tables in BigQuery from operational systems on a continuous schedule

History that outlives the tool

A continuously synced copy in BigQuery preserves a queryable record even as data ages out of Microsoft 365 or gets changed inside it.

Analytics on Microsoft 365's data

Records and events from Microsoft 365 land in BigQuery 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.

What you can sync between BigQuery 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.

BigQuery objects Microsoft 365 objects
Projects Connection scope: the service account grants access per project. Users Entra ID user accounts synced with HR and identity systems.
Tables The syncable unit: only tables can be synced per the Stacksync docs. Groups Microsoft 365 and security groups kept aligned with org structure and access rules.
Partitioned tables Synced like regular tables; partition columns map to target fields. Mail Messages Exchange Online messages read for logging, archiving, or activity capture.
Clustered tables Supported; clustering is transparent to the sync. Calendar Events Events synced with scheduling tools and CRMs for meeting visibility.
Datasets Organizational container — you pick which dataset’s tables to sync. Contacts Personal and org contacts kept consistent with CRM contact records.
