“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.”
Salesforce‘s Data Import Wizard has a hard 50,000 record limit and frequently times out with files over 5-10MB. When it fails partway through, you’re left guessing where the process stopped and which records actually made it into your system.
Here’s how to handle large Excel lead files without hitting these limitations or dealing with timeout failures.
Process large files with batch importing using Coefficient
Coefficientbreaks your large dataset into configurable batches (default 1,000 records, up to 10,000) and processes them in parallel. This prevents the timeout issues that plague the Data Import Wizard and gives you clear tracking of which records succeeded or failed.
How to make it work
Step 1. Upload your large Excel file to Google Sheets.
Google Sheets doesn’t have the same file size restrictions as the Data Import Wizard. Upload your entire Excel file regardless of size and let Google Sheets handle the data processing.
Step 2. Connect Coefficient to your Salesforce org.
Install Coefficient and authorize your Salesforce connection. This gives you access to more efficient API methods than what the Data Import Wizard uses.
Step 3. Configure batch processing settings.
In Coefficient’s export settings, set your batch size to 1,000 records (or smaller if you’re still experiencing issues). Enable parallel batch execution to process multiple batches simultaneously for faster completion.
Step 4. Map your fields and preview the import.
Map your Excel columns to Salesforce Lead fields and run a preview to catch any validation issues. This prevents failed batches due to data problems that the Data Import Wizard wouldn’t catch until after processing.
Step 5. Execute the batched import with progress tracking.
Run the import and monitor progress through Coefficient’s results tracking. You’ll see exactly which batches completed successfully and can retry any failed batches without reprocessing successful records.
Import large datasets without the guesswork
Start using CoefficientBatch processing with clear progress tracking eliminates the uncertainty of large file imports. You’ll know exactly what succeeded and what needs attention.to handle large Excel lead files reliably.
