Upload your own codes (CSV)

Already have codes? Select a discount, choose Upload codes, and drop in a CSV. CodeBulk creates a job and imports your codes into the discount, just as it does for generated ones. The job’s title is the file’s name.

The file

• A CSV file, one at a time.
• The header row must have a Coupon column.
• One code per row, each up to 255 characters, using only letters, digits, _ and -.
• Empty lines are skipped, and a UTF-8 BOM at the start is fine.

How uploaded codes are used

Uploaded codes go in exactly as written: CodeBulk doesn’t uppercase them or remove duplicates. They count toward the free allowance in the same way as generated codes.
