Weight, dimension, and volume metafields now export as a number and a unit, like 12 kg or 1.5 in. Before, the export showed the JSON that Shopify stores, like {"value":12.0,"unit":"kg"}. That works for a computer but it’s harder to read and edit in a spreadsheet.
You can upload the same format back as a spreadsheet edit. The unit isn’t case sensitive and the space is optional, so 12 kg, 12KG, and 12 kilograms all work. You can use short units like cm and lb or full names like centimeters and pounds. The JSON format still works too, so your older spreadsheets import the same as before.
When a value can’t be used, the edit now tells you why. For example, the unit is missing, the unit doesn’t match the metafield (a weight unit on a dimension metafield), or the number has a comma (use 1.5, not 1,5). Each problem has its own error code, and the steps to fix it are in the error codes article.
