# CSV Encoding

When downloading data in CSV format, there are some values that need to be quoted. Extole uses the following algorithm for determining which values to quote:

1. If the value contains a comma or any ASCII character lower than a comma - this includes a space and `,!"#$%&'()*+`
2. If the value is longer than 24 characters

Here are some examples:

| **Value in CSV File** | **Reason for Quoting** |
| - | - |
| [test@example.com](mailto:test@example.com)[](mailto:test@example.com) | None |
| "[johnrichardsdoe@example.com](mailto:johnrichardsdoe@example.com)[](mailto:johnrichardsdoe@example.com)" | Over 24 characters |
| "coupon1,coupon2" | Comma in value |
| "United States" | Space in value |
| refer-a-friend | None |
| "[test+1@example.com](mailto:test+1@example.com)[](mailto:test+1@example.com)" | Plus in value |
