+To import issues, GitLab requires CSV files have a specific format:
 
-- **header row:** CSV files must include the following headers:

-- **columns:** Data from columns beyond `title` and `description` are not imported.
-- **separators:** The column separator is automatically detected from the header row.
-  Supported separator characters are: commas (`,`), semicolons (`;`), and tabs (`\t`).

-- **double-quote character:** The double-quote (`"`) character is used to quote fields,

-  field, use two double-quote characters in succession (`""`).
-- **data rows:** After the header row, succeeding rows must follow the same column
-  order. The issue title is required while the description is optional.
