Free Catalog Converter

List on another marketplace without retyping. Give us your product sheet and the blank upload template of the channel you want; we fill every column we can, check values against the template's own lists, and tell you exactly what is still missing per product.

Both files are read in your browser and are not uploaded. The filled template keeps the channel's own dropdowns, formulas and macros: only the product cells are written. If an upload is still rejected, paste the rows from "rows to paste" into a fresh template. AI text is written only from facts in your sheet, never with new numbers or claims; check it before uploading.
