Excel Online Data Integration

Overview

Excel Online integration for Drupal bridges the gap between structured spreadsheet data and your content management system. This powerful solution enables real-time data synchronization, embedded spreadsheet editors, and automated reporting workflows using Microsoft Graph API.

Features

• Read and write Excel data via Graph API
• Inline spreadsheet editor embedded in Drupal
• Automated data import and export
• Scheduled exports for reporting
• Cell-level data validation
• Formula preservation and calculation
• Multiple worksheet support
• Excel template management

Technical Details

Technologies: Microsoft Graph API, Excel Online API, Drupal Field API, Drupal Entity API, Drupal Cron, JavaScript Office.js

Requirements:

• Drupal 9.x or 10.x
• Microsoft 365 with Excel Online
• Azure AD app with Files.ReadWrite permission
• OneDrive or SharePoint for file storage
• Modern browser with JavaScript enabled

API Endpoints:

Get worksheet: GET /me/drive/items/{item-id}/workbook/worksheets/{sheet-name}
Get range: GET /me/drive/items/{item-id}/workbook/worksheets/{sheet-name}/range(address='{range}')
Update range: PATCH /me/drive/items/{item-id}/workbook/worksheets/{sheet-name}/range(address='{range}')
Add table: POST /me/drive/items/{item-id}/workbook/tables/add

Implementation

1. Configure Azure AD app with Excel API permissions
2. Create custom field type for Excel data
3. Implement Graph API client for Excel operations
4. Build inline editor widget with Office.js
5. Create import/export service
6. Set up scheduled cron jobs for exports
7. Implement data validation and transformation
8. Add template management system
9. Configure range mapping for data sync
10. Build admin UI for Excel file selection
