 Audience CSVs are generated on demand. Before you can download the CSV, you will need to generate it. There are three different options for formatting:
 
-- **Unformatted:** Contains two columns. The first contains the user or account key and the second is a JSON object containing the external IDs. Generating this CSV is by far the fastest of the three options. [Download example unformatted CSV](files/audience_csv_format_a.csv)
-- **Distinct columns for unique external IDs (with indexed columns for ID types with multiple values):** Contains the same first two columns as the unformatted CSV. Additional columns are added for each distinct external ID type. When a given external ID type has more than one value, for example a user with three email addresses, _additional columns with indexed headers are added_, (`email`, `email_1`, `email_2`). [Download example formatted CSV with indexed columns](files/audience_csv_format_b.csv)
-- **Distinct columns for unique external IDs (with additional rows for ID types with multiple values):** Contains the same first two columns as the unformatted CSV. Additional columns are added for each distinct external ID type. When a given external ID type has more than one value, for example a user with two email addresses, _additional rows are added with the first two columns repeated (user or account key and external IDs JSON)._ [Download example formatted CSV with additional rows](files/audience_csv_format_c.csv)

When a given external ID type has more than one value, for example a user with three email addresses, _additional columns with indexed headers are added_, (`email`, `email_1`, `email_2`). [Download example formatted CSV with indexed columns](files/audience_csv_format_b.csv)
+- **Single Column (with one external ID type):** Contains only a single column of data with the selected external ID type. When the given external ID type has more than one value, for example a user with two email addresses, _additional rows are added._ Data in this format is hashed by default with the SHA256 hashing algorithm, but may be downloaded raw (unhashed) with appropriate permissions. This format is useful for uploading the audience to destinations like Snapchat or Braze, which may require a single column of hashed emails, for example.
