+# Importing Issues from CSV
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/23532) in GitLab 11.7.
+
+Issues can be imported by uploading a CSV file. The file will be processed in the background and a notification email
+will be sent to you once the import is completed.
+
+> **Note:** A permission level of `Developer` or higher is required to import issues.
+
+## CSV File Format
+
+### Header row
+
+CSV files must contain a header row with at least two columns: `title` and `description`, in that order.
+
+### Column separator
+
+The column separator is automatically detected from the header row.
+
+Supported separator characters are: commas (`,`), semicolons (`;`), and tabs (`\t`).
+
+### Row separator
+
+Lines ending in either `CRLF` or `LF` are supported.
+
+### Quote character
+
+The double-quote (`"`) character is used to quote fields so you can use the column separator within a field. To insert
+a double-quote (`"`) within a quoted field, use two double-quote characters in succession, i.e. `""`.
+
+### Data rows
+
+After the header row, succeeding rows must follow the same column order. The issue title is required while the
+description is optional.
+
+The user uploading the CSV file will be set as the author of the imported issues.
+
+## Sample Data
+
+```csv
+title,description
+My Issue Title,My Issue Description
+Another Title,"A description, with a comma"
+"One More Title","One More Description"
+```
