With the customer data import tool, you can create new customers and contacts, and add data to existing customers (with certain restrictions).

Customer name is the only mandatory field.

The easiest way to get started is by downloading the template file from the path Settings > Data imports > Customer import. The template file contains columns for possible additional data and examples of how the data should be formatted in the CSV file. You can also use a self-created file, but ensure that its first row is the header row of the data to be imported.

You can use the customer data import to add data and Settings to existing customers. Data that can be added:

  • Addresses
  • Contacts
  • Industries
  • Contact roles
  • Contact keywords
  • Customer groups

To add data, enter the customer name as an identifier on each row and input the desired data into the columns.

Admin permissions are required for data imports.

Notes before start

  • Customer data can be imported using a CSV file
  • CSV files can be created and edited with spreadsheet software
  • Do not use double quotes ("), semicolons (;) or line breaks (Enter) in your data
  • Use semicolon (;) as a separator in the file
  • Special characters, including Ä, Ö, Å, need to be encoded according to ISO/IEC 8859-1, Windows-1252, or UTC-8 standards.

Import data

  1. Go to Settings > Data imports > Customer import
  2. Select the file you want to import from your computer (drag and drop the file into the box or browse files)
  3. Check the status of the file contents in the Import data view and fix possible errors
  4. In the Settings section, you have the possibility to approve:
    • Adding new values to Customer settings.
    • Updating existing customer's data. Note that modifying or deleting added settings, contacts, customer groups, or any other added data is not possible.
  5. Click the Import data button after checking the data
  6. After a successful import, a list of imported customers and contacts will appear
    • If you receive error messages at this stage, correct the data or remove the row, and try the import again.
