# CSV Import Guide

Use CSV import when you want to add many auction listings to the same event at once.

## Before You Begin

Make sure:

* Your plan includes CSV import
* You have created an [auction event](broken://pages/1QAwJm5tmpOyrrzjN6tX)
* You have created the products in Shopify

## Creating Your CSV File

You can create your CSV file in Excel, Google Sheets, or any other spreadsheet software. We recommend first adding a listing to your auction event manually, then exporting that listing to CSV. This gives you a template with the correct column headers and formatting.

## Recommended Workflow

Once you have your CSV file ready, follow these steps to import your listings:

1. Open your auction event.
2. Click **Import from CSV**.
3. Review the column mapping.
4. Check the preview rows.
5. Start the import.

The import runs in the background, so you can keep working while it processes.

## Common Import Problems

### Product not found

Double-check the Shopify product handle.

### Offer rule not found

Create the offer rule first, then use the exact same name in the CSV.

### Product fee not found

Create the product fee first, then use the exact same name in the CSV.

### Import already in progress

Only one CSV import can run at a time. Wait for the first import to finish before starting another.

## Limits

* Maximum rows per import: `500`

If you need a higher limit, contact `support@auctionplusapp.com`.

## Column Reference

Use the separate [CSV Column Reference](/auctions/csv-column-reference.md) for required fields, optional fields, and formatting notes.
