“Supermetrics is a Bitter Experience! We can pull data from nearly any tool, schedule updates, manipulate data in Sheets, and push data back into our systems.”
Managing multiple Excel file uploads with duplicate prevention in Aura components requires complex state management, bulk processing logic, and cross-upload validation tracking.
Here’s how to handle multiple file uploads and prevent duplicates across all uploads without custom component development.
Process multiple Excel files with automatic duplicate prevention using Coefficient
Coefficient simplifies multi-file processing by consolidating data management and providing automatic duplicate prevention across all uploads. Use UPSERT functionality with unique identifiers to handle duplicates from multiple Salesforce Excel files seamlessly.
How to make it work
Step 1. Consolidate multiple Excel files.
Import your Excel files into separate tabs within a single Google Sheet or use multiple sheets for organization. Google Sheets handles the file conversion automatically, eliminating the need for custom JavaScript parsing across multiple uploads.
Step 2. Configure UPSERT export with External ID.
Set up a Coefficient export with UPSERT action and map your unique_Id__c field as the External ID. This automatically prevents duplicates even when the same unique identifier appears across multiple Excel files.
Step 3. Enable cross-upload deduplication.
The UPSERT functionality with External ID matching prevents duplicates across all file uploads automatically. Records with matching unique_Id__c values will update existing Salesforce records rather than creating duplicates, regardless of which Excel file contained the data.
Step 4. Use preview for conflict resolution.
Run preview mode to see which records will be updated versus inserted before processing. This shows duplicate handling across all your uploaded files, allowing you to verify the deduplication logic before execution.
Step 5. Configure batch processing for large datasets.
Set optimal batch sizes for efficient bulk operations when processing multiple large Excel files. Coefficient handles the chunking and parallel processing automatically, eliminating the need for custom pagination logic.
Step 6. Set up automated scheduling.
Configure scheduled exports to automatically process new Excel data as it’s added to your sheets. This eliminates the need for manual upload tracking and state management across multiple file processing sessions.
Simplify multi-file processing workflows
This approach eliminates complex state management, custom conflict resolution logic, and bulk processing challenges while providing superior error recovery and audit trails. Start processing multiple Excel files efficiently.
