Which formats does Facebook accept for uploading customer data?

Facebook accepts several formats for uploading customer data to create a custom audience. Here are the acceptable file formats:

1. Comma-separated values (CSV) file: This is the most common file format for uploading customer data to Facebook. Make sure to save your CSV file with UTF-8 encoding to avoid any issues with special characters.
2. Tab-separated values (TSV) file: Similar to a CSV file, a TSV file uses tabs instead of commas to separate the data fields.
3. Copy and paste: If you only have a small number of customers in your database, you can copy and paste their data directly into the Facebook Ads Manager interface.
4. Mailchimp integration: If you use Mailchimp for your email marketing, you can connect your Mailchimp account to Facebook and create a custom audience directly from your Mailchimp audience lists.
5. Customer relationship management (CRM) platform integration: If you use a CRM platform like Salesforce or HubSpot, you can connect your CRM account to Facebook and create a custom audience directly from your CRM data.

When preparing your customer data for upload, make sure to use a unique identifier for each customer, such as an email address or phone number. Facebook requires that you have proper consent from your customers to use their data for advertising purposes, so be sure to review Facebook's custom audience terms and conditions before uploading your data.
