How to merge crm export csvs
- Step 1Export contacts or deals from each CRM — Request CSV exports from each system. Salesforce uses Reports, HubSpot uses the Contacts export link, Pipedrive uses the import/export settings.
- Step 2Drop the files into the merger — Add each export. The tool reads all headers and builds a unified column set.
- Step 3Confirm the row and column counts — The preview shows total rows in vs total rows out so you can spot any truncation before downloading.
- Step 4Import the merged file — Download the combined CSV and import into your target CRM, data warehouse, or analytics tool.
Frequently asked questions
What happens when Salesforce and HubSpot use different names for the same field?+
They are treated as separate columns. If you want them merged, rename headers to match using the CSV Header Rename tool first.
Is this safe for GDPR-covered contact data?+
Data never leaves your browser, which keeps it off any third-party servers. Always apply your own GDPR obligations when handling personal data.
Can I merge more than two CRM exports?+
