The most common issues encountered during product data import are "inconsistent formatting" and "unclear field semantics." We recommend addressing three key areas in preparation: First, standardize SKU format to ensure the same product uses the same code across all spreadsheets, avoiding situations where one item has multiple codes or one code represents multiple items. Second, organize specification text scattered across remarks into filterable tags—such as material, size, and applicable voltage—so customers can filter by conditions on the product page. Third, verify the correspondence between images and SKUs to prevent mismatches after import. If your source data has messy fields to begin with, do one round of data cleaning before import rather than correcting after, which saves considerably more effort.
