You can easily import prospects into Overloop from a file. The import flow has four steps: Upload → Field Mapping → Configuration → Preview.
From the Prospect Hub
Go to your Prospects hub.
Click New Prospect.
You’ll see three options for how you’d like to add new prospects and you can select the third option “Import New File”.
From Settings
Go to Settings > Import.
Click New Import to begin.
Uploading Your File
Once you’ve started a new import, you can either:
Drag and drop your document into the window, or
Select a file from your computer.
📎 File requirements:
Supported file formats:
.csvand.xlsxMaximum size: 10MB → If your file is larger, split it into smaller files (e.g. using filesplit.org)
Sheet limitation: Only the first sheet of your file will be processed. If you have multiple sheets, move the data you want to import to the first sheet or split the sheets into separate files.
Field Mapping
In this step, match the columns in your file with Overloop’s fields (e.g., first name, last name, email, company).
Mapping List
If your file contains a column for Lists (e.g., “CEO”, “Event leads”), you can map it:
Map the Lists column from your file to the Lists field in Overloop.
The mapped list names will automatically add those prospects to the corresponding lists in Overloop or create a new list if it doesn’t exist yet.
Configuration
In the Configuration step, you can define how imported prospects should be enriched, assigned, and handled. You can also choose to enroll them in a campaign or add them to an existing list during this step.
Preview
In the final step, you’ll see a preview of the data that will be imported into Overloop:
