How to Read Excel Data in SharePoint Without Downloading the File

Product: SharePoint and Microsoft Excel
Device & OS: not provided
Scenario: Developing an application, automated flow, or integration that requires extracting specific ranges, tables, or worksheets from an online SharePoint Excel file.
Observed behavior: Standard SharePoint file download endpoints retrieve the entire workbook instead of returning the specific data content contained within the worksheets.

Before you start

Ensure you have the necessary Microsoft Graph API permissions configured (such as Files.Read.All or Sites.Read.All) in Microsoft Entra ID, and note the target SharePoint Site ID and Drive ID.

Solution 1Recommended

Use Microsoft Graph Excel Workbook APIs

The recommended approach is to utilize the Microsoft Graph API, which is specifically designed to interact with the contents of an Excel workbook hosted on SharePoint or OneDrive.

Microsoft Graph provides dedicated REST API endpoints that allow developers to read worksheets, ranges, tables, and charts inside an Excel workbook without downloading the physical file. This approach is highly efficient and saves significant bandwidth.

Authenticate the API request

Obtain an access token using OAuth 2.0 via Microsoft Entra ID (formerly Azure AD) with the appropriate delegated or application permissions.

Construct the base URL

Target the specific Excel file in your SharePoint document library by formatting the URL as: https://graph.microsoft.com/v1.0/sites/{site-id}/drives/{drive-id}/items/{item-id}/workbook/.

Append the specific Excel endpoint

To read a specific range of data, append '/worksheets/{sheet-id-or-name}/range(address='A1:B10')' to the base URL and execute a GET request.

Efficient Data Retrieval: Using the Microsoft Graph API ensures that only the requested data is returned in a lightweight JSON format, completely bypassing file downloads.

Consult the Microsoft Q&A Community for Advanced Guidance

If you encounter implementation-specific errors or require custom coding solutions, engaging with the official Microsoft developer community is the best next step.

Frequently Asked Questions

Can I use the legacy SharePoint REST API to read Excel cells directly?

No, the legacy SharePoint REST API mainly handles file metadata, list items, and complete file downloads. To read specific cell values or ranges within an Excel file, you must use the Microsoft Graph Excel APIs.

What Excel file formats does the Microsoft Graph API support?

The Microsoft Graph Excel API primarily supports modern Excel workbooks (.xlsx) stored in SharePoint, OneDrive, or Microsoft 365 Groups. Older binary formats (.xls) are not supported.

Do I need special permissions to read SharePoint Excel data via API?

Yes, your application requires appropriate Microsoft Graph permissions, such as Files.Read.All or Sites.Read.All, which typically need to be granted by an Entra ID administrator.

Is there a limit to how much data I can request at once using the Graph API?

Yes, the Microsoft Graph API has request payload size limits and timeouts. It is recommended to request smaller, specific ranges of data or use pagination if retrieving massive datasets.
