## Add a new Contact list

To add an attribute in bulk to a new list of contacts into WATI, we need to:


1. Access the "Contacts" screen, click "Import" button and then click on the 'Download Sample CSV' to download the Contacts sample file

2. Fill data into the file: the sample file already containing Name, CountryCode, Phone, Required Attributes: Allow Broadcast and Allow SMS, two sample columns of inputting attributes (Attribute 1 and Attribute 2)

* Allow Broadcast: If set to TRUE, allows this contact to receive the broadcast messages
* Allow SMS: If set to TRUE, allows this contact to receive the SMS messages(not available in Growth and Pro plan)
* For attributes, from column F onwards, the user can input attributes. Attribute column is a attribute name and value in the row is the attribute's value
* If with that attribute, the contact doesn't have any data, the user can leave it blank

3. Select the Import button again, click on 'Browse files' option and select the CSV file to upload the inputted file and new imported contacts will be displayed with full attributes

## Update attributes of existing contacts

To update attributes of existing contacts, firstly user need to download existing contact to csv file by selecting the "Export to CSV" button:

 ![](https://brainfish-storage-prod.s3.us-east-2.amazonaws.com/uploads/89bf6e1f-2201-41c2-b229-35494ad335e9/0c13112b-8bab-4b16-8137-6519eeb2c2f4/migrated?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAUPPN5IL3QLQZLDSU%2F20250715%2Fus-east-2%2Fs3%2Faws4_request&X-Amz-Date=20250715T213348Z&X-Amz-Expires=3000&X-Amz-Signature=e1a7e5b9024b3665bc5c439fff3c6273aec7dd2137fc119d0ae819627a7cec90&X-Amz-SignedHeaders=host&response-content-disposition=attachment)

After download, the csv file will contain the full list of contacts and their attributes.

You can then update old attributes and amend new attributes data, by following step 2 and 3 above in case you want to create and update attributes of new contacts.

After updating the data in the file you can import it again and then select 'Update records' or 'Skip records' option in the import screen.

For more information please check this article: <https://wati.brainfish.ai/articles/how-to-import-contacts-to-wati-2DQwsGQngv>

:::

"Update records" means when uploading the file, if the contact is duplicated, it will use new data from the csv file. "Skip records" means if the contact is duplicated, it will keep old data from being overwritten.

If you want to add an attribute into the bulk of existing contacts, then you need to choose "Update records".
