Key Benefits of Preparing Your CSV File


Taking the time to format your CSV file correctly before importing ensures your contact data is clean, complete, and mapped accurately.


  • Reduces the chance of import errors or upload failures

  • Helps HighLevel automatically map fields during import

  • Enables contact deduplication and accurate updates

  • Supports custom fields and advanced segmentation

  • Saves time by avoiding post-import cleanup

  • Increases success with bulk contact/opportunity uploads

What is a CSV File Format?


CSV stands for 'Comma-Separated Values'. It's a simple file format used to store tabular data like spreadsheets or databases. Each line in a CSV file represents a single record, and fields within the record are separated by commas. It’s one of the most widely used formats for importing and exporting data between different systems.


  • CSV files typically have a .csv extension.

  • You can create or edit them in tools like Excel, Google Sheets, or Notepad.

  • Ensure only one sheet is present in the file to prevent import issues.

Example:


First NameLast NameEmailPhone
JaneDoejane@example.com+11234567890
JohnSmithjohn@example.com+10987654321

Structuring Your File


To ensure accurate data mapping, structure your CSV file with column headers corresponding to standard or custom fields in HighLevel.


1. Sample CSV Format


First NameLast NameEmailPhoneCompanyTagsStatusCreated DateAdditional Phone
JohnDoejohn@example.com+11234567890ABC CorpVIP, LeadNew01/01/2024+17877123462
JaneSmithjane@example.com+15556667777XYZ LtdCustomerActive02/02/2024+17877123464


  • Each row represents a single contact or opportunity.

  • Each column represents a distinct property.

  • The header row is required to map fields correctly.


2. Mandatory Fields


At least one of the following is required to create or update a contact:

  • First Name

  • Email Address

  • Phone Number


Note: For updating contacts, a Unique Identifier (Contact ID, Email, or Phone) is required based on your deduplication settings. For opportunities, include the Opportunity ID if updating. Without it, a new one will be created.

Tip: Before importing your CSV, ensure custom fields are already created in your HighLevel account using the same labels and data types.For help with creating custom fields, refer to Overview of Merge Fields & Custom Variables

Supported Countries List in CSV Imports


This section contains a table of country names accepted during CSV imports into HighLevel. These are the official country values that should be used in your CSV file when mapping a country field, whether standard or custom. Use the exact country names or short codes listed below in your CSV file.


  • Purpose: HighLevel validates country names during import. If your CSV includes a Country field, each row must match one of the exact names in this list.

  • Format: Must match exactly—case-sensitive and spelling-sensitive. For example, United States is accepted, but USA or U.S. will cause an error.

  • Custom Field Use: If you're using a custom country field, you can still benefit from sticking to this list to maintain compatibility.

Frequently Asked Questions


Q: Can I import contacts with more than one phone number or email?
Yes! Use separate columns like Additional phone numbers and Additional email addresses, and separate entries with commas.



Q: What happens if I include a field in the CSV that doesn’t exist in HighLevel?
That field will be ignored unless you map it to an existing standard or custom field during the import process.



Q: Will HighLevel detect duplicates automatically?
Yes, based on your Duplicate Detection Settings, it can match by Contact ID, phone, or email and either merge or skip duplicates.



Q: Can I update contacts with a CSV import?
Absolutely. Just make sure you're including a field used in your duplicate matching (like Contact ID, email, or phone).



Q: Do I need to clean blank rows and columns?
Yes. It’s best to remove all unnecessary data to avoid unexpected import behavior.
