PRODUCT INFORMATION

Help and product limitations

Getting started

Choose either the custom CSV column mapper or the Shopify new-simple-product preset. Upload a CSV, TSV or XLSX file of up to 5 MB and up to 10,000 rows; or load our synthetic example. For CSV files, the tool attempts to detect the delimiter. For XLSX, the first worksheet is read, without macros or formula calculation.

Custom column mapping

Upload your source file. Enter your output header names or upload a destination CSV/XLSX template to use its headers. Select where each output column's data comes from. Review the before/after preview and export a new CSV or XLSX file. Save a recipe in browser storage to reuse the mapping with new source data. Recipe JSON backup/restore is available on the mapping screen.

Shopify preset

The Shopify mode exports new simple products as drafts. It does not update existing products, stock levels, warehouse locations, variants, barcodes, or multi-location inventory. Please see Shopify's official product CSV help and Shopify inventory CSV guidance. Test with a few draft items on a development store before any important import.

Important formatting

SKUs and other identifiers are preserved as text when source cells contain text. Numeric cell formatting in complex XLSX documents may not survive conversion, so double-check IDs. Prices must use plain non-negative decimals with a clearly chosen dot or comma. Blank prices remain blank; ambiguous prices produce validation issues. Rows with errors are excluded from the file.

Security and privacy

Uploaded files are processed in browser memory; we do not intentionally send their contents to our server. Text cells that look like Excel formulas are neutralized for CSV export; XLSX exports store them as string cells. This tool does not support macro workbooks.

Known limits

Custom recipe storage is local to the same browser/device. We do not provide online sync, scheduled imports, customer accounts, billing, direct Shopify connection, or support for all Excel formulas, merged cells and complex formatting. If the first worksheet isn't the source data, save the required sheet as its own CSV before using the tool.
