“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 times out frequently with files over 5-10MB or when processing complex validation rules. When timeouts happen, the wizard fails without clear recovery options, leaving you unsure which records processed successfully.
Here’s how to import large Excel lead files without timeout failures.
Avoid timeouts with batch processing using Coefficient
Coefficientuses configurable batch processing (default 1,000 records, max 10,000) with automatic retry mechanisms for temporary API issues. This prevents the large single-transaction timeouts that cause the Data Import Wizard to fail.
How to make it work
Step 1. Upload your Excel file to Google Sheets without size restrictions.
Google Sheets handles large files better than the Data Import Wizard’s file size limitations. Upload your entire Excel dataset regardless of size.
Step 2. Configure smaller batch sizes for problematic datasets.
In Coefficient’s export settings, reduce batch size to 500-1,000 records for datasets that have caused timeout issues. Smaller batches process faster and are less likely to hit timeout limits.
Step 3. Enable parallel processing for faster completion.
SalesforceTurn on parallel batch execution in Coefficient’s advanced settings. This processes multiple batches simultaneously while staying withinAPI limits, improving overall performance.
Step 4. Schedule imports during off-peak hours.
Use Coefficient’s scheduled export feature to run imports when Salesforce performance is optimal. This reduces the likelihood of timeout issues caused by high system load.
Step 5. Monitor progress with results tracking.
Track which batches complete successfully through Coefficient’s progress monitoring. If any batches fail due to temporary issues, you can retry them without reprocessing successful records.
Process large datasets reliably
Try CoefficientBatch processing with automatic retry eliminates the frustration of timeout failures and gives you clear visibility into import progress. No more guessing which records made it through.to handle large Excel lead imports without timeout issues.
