Click the "Update item list" button on the item list screen, then click "Download the template for upload" on the next screen.

Rules for entering item list files

Don't remove the header name. Don't enclose the header name with " " (double quotation marks)

You can't remove the header name on the item list file. For the unnecessary item, enter the header name on the first row and leave other rows blank. Don't enclose the header name with " " (double quotation marks).

Don't create multiple rows for the same item ID.

If multiple rows exist for one item ID, we cannot guarantee which row will be applied in the ad displayed.

Even if the item is displayed in the ad, it may not be displayed depending on the display format of the ad.

Some parts of ad creatives may be displayed.

Item names and item descriptions may be displayed partially on the ads.

Change URL when changing the image (the old image is cached).

When changing the image file on updating the item list, update the image URL itself. If you replace the image with the same image URL, the older image may be displayed on the ad.

When multiple prices are in the item list, the formatted sale price is used. The following order shows which price appears.

1. Formatted Sale Price (most prioritized)

2. Sale Price
3. Formatted Price
4. Price
*We recommend not to use "Sale Price" and "Price" when using "Formatted Sale Price" and "Formatted Price" and contrariwise.

"Sale Price" and "Price" are displayed together with the words ($、円、(税込), etc.) set in the setting item "Prefix" or "Suffix" of the ads.


When neither the price prefix nor the suffix is set, "¥" (double-byte) is automatically inserted before the price as for the price information.

When changing (updating) the item list the timing to take effect varies between items.

When changing multiple items the former item and the changed item may be displayed in one ad. "Display setting" and "Stock information" are changed with priority.
