Use cases

Why sync Excel to Azure SQL Database?
Ready for analysis.

Centralizing your Excel data in Azure SQL Database lets you join it with other data sources for cross-platform analytics and deeper insights.

Build reliable dashboards and reports by querying Excel data directly in Azure SQL Database using SQL or your preferred BI tool.

  • Centralized data warehouse

    Bring Excel data into Azure SQL Database alongside other sources to create a single source of truth for your organization.

  • Automated reporting

    Replace manual exports and spreadsheet-based reporting with automated pipelines from Excel to Azure SQL Database. Connect BI tools like Looker, Metabase, or Power BI.

Data

What data can you sync?
From Excel to Azure SQL Database.

Weld syncs the following data objects from Excel into Azure SQL Database. The exact tables and fields depend on your Excel configuration and the permissions granted during setup.

  • Worksheets
  • Rows
  • Named Ranges
Weld MCP server

Ask your agent.
It queries Azure SQL Database for you.

Connect Claude, Cursor, ChatGPT or your own agent to Weld over MCP. It reads the Excel context, finds the tables it needs and runs the query in Azure SQL Database.

Reverse ETL

ELT vs. reverse ETL: Excel and Azure SQL Database

ELT (Extract, Load, Transform) moves data from Excel into Azure SQL Database for analysis. This is the approach shown on this page, and the one to use for dashboards, reports, and data models.

Reverse ETL works the other direction: it pushes enriched data from Azure SQL Database back into Excel. For example, you could sync computed lead scores or customer segments from your warehouse into Excel to personalize outreach.

Weld supports both directions, so you can build a complete data loop between Excel and Azure SQL Database.

Azure SQL Database to Excel
Incremental syncing
Weld uses incremental syncing where supported by the Excel API, loading only new and updated records to minimize data transfer and warehouse costs.
Schema handling
Weld automatically manages schema changes. If Excel adds new fields, they're detected and added to the corresponding Azure SQL Database tables.
Data freshness
Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
Security
All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
