1. Prepare CSV File

When creating a CSV file, ensure it meets the following requirements:

Parameter	Allowed Values
Encoding	UTF-8
Line separator	CRLF
Values delimiter	Comma
File extension	.csv
Compression	.gz, .zip
Headers	Yes

A CSV file should contain at least one data row and at least one of the following columns. You can either upload your file unhashed (as it will automatically be hashed in the browser). If you wish you to hash the data beforehand, you can apply the SHA256 algorithm. Please follow the formatting guidelines for emails and phone numbers before hashing.

• email address

• phone number

• address (You should not hash the postal addresses yourself. We need to format them ourselves to properly match the data)

• personal ID (Sweden only)
