Delimited Text File

A plain-text file, such as CSV or TSV, in which fields are separated by a delimiter and records by line breaks.

Definition

CSV is universal but has no schema, types or compression, and it struggles with embedded delimiters, quotes, encodings and headers. Loaders need file format options such as delimiter, header skipping, quote character and NULL representation.

Example

FIELD_OPTIONALLY_ENCLOSED_BY = '"' in a Snowflake CSV file format

Exam tip

Load failures from commas inside values are fixed by setting the quote or enclosure character.
