TikTok Bulk
Turn a Mockup Processor batch into a TikTok Shop bulk-upload xlsx, ready to upload in Seller Center.
How this works
- Process designs in Mockup Processor — that writes a batch CSV inside your output folder.
- Download a fresh blank template from TikTok Seller Center → Add Product → Bulk upload → T-shirts category.
- Load the batch CSV here, upload your blank template, and the page lists every design that has T-shirt mockups.
- Fill in title, description, price, brand. Mark each design as Adult or Kids and pick which mockup images go in.
- Click Generate — you get a TikTok-ready
.xlsx(or zipped Adult+Kids pair) to upload.
Things worth knowing before you start
- One template = one category. TikTok splits Adult, Women's and Kids' T-shirts into different categories. To list both Adult + Kids, switch to Produce Both mode below and upload one template per age band — the page outputs a zip with separate xlsx files.
- Responsible Person ID (UK GPSR). TikTok requires an RP ID on apparel listings. Set it once in Defaults and every row picks it up.
- Brand must match the template. The Brand sheet inside the template lists only brands you've registered in Seller Center. The dropdown on each design uses that list.
This page does not post to TikTok directly — you upload the xlsx yourself. First-time setup? See the TikTok setup guide (account, brand registration, RP ID).
