COMMON QUESTIONS
Important things to know
Are files uploaded to RepeatKit servers?
No. The converter runs in your browser. This website may still generate ordinary hosting access logs, but uploaded file contents are not intentionally transmitted to a backend.
Can I convert an Excel .xlsx file?
Yes, the current browser version supports CSV, TSV and common XLSX worksheets. It reads the first sheet only. It does not run macros or calculate spreadsheet formulas. Complex formats may need a CSV export.
Can I update existing Shopify inventory?
No. The Shopify preset is strictly for creating NEW simple draft products, not stock levels, locations, existing products or variants. Shopify maintains a separate inventory CSV flow.
Where are saved mapping recipes stored?
They are stored in this browser's local storage. Clearing site data will erase them. Download a JSON backup from the mapping screen. Uploaded spreadsheets are not saved.
Is this ready for important production imports?
Always review the output and try a small import on a Shopify development store first. This independent utility cannot guarantee compatibility with every merchant-specific configuration.
Need a different kind of file mapping?
Choose the universal mapper, or use our narrow Shopify new-product preset.
