Frequently asked questions
What is the difference between a Salesforce field label and API name?+
Labels are human-readable ('First Name'). API names are the programmatic identifiers ('FirstName'). Import tools match by API name.
Can I rename headers for custom Salesforce fields?+
Yes. Custom field API names usually end in '__c' (e.g. 'Lead_Source__c'). Type those exactly.
Does renaming headers change any row data?+
No. Only the header row values change. All data rows are preserved exactly.
