Avoid upload errors

420g0.42

Weights in kg and sizes in cm, with no units or spaces.

TRUE or FALSE

YTRUE

No gaps in required columns

Every row needs a StockCode and Name, and a Weight for new products.

Leave our columns blank. The template includes columns that only our team uses. Leave these empty and we’ll set them for you:

Questions

Common questions.

“Invalid Spreadsheet Format: The conversion cannot be performed”

There’s text in a number column, a stray space, or a required cell is empty. Check weights and sizes are numbers only, yes/no columns use TRUE or FALSE, and every row has a StockCode and Name.

How do I update products I’ve already added?

Use the same template. Fill in the StockCode and only the columns you want to change. Blank columns are ignored, so nothing else is overwritten.

How do I change a SKU?

Put the current SKU in StockCode and the new one in the NewSKU column. Remember to change it in your webshop too.

I updated a discontinued product and it became active again

When updating a discontinued product, put TRUE in the Discontinued column. If it’s left blank, the product is made active again.

My upload hasn’t appeared yet

Uploads run in the background and can take up to 10 to 15 minutes. You’ll get an email when they’re done.

Can I upload products for more than one brand at once?

No, each upload is for one account. Upload a separate file for each brand.
