Frequently asked questions
Does this update my Shopify store?
No. This tool creates comparison and exception reports only. Native Shopify import files are intentionally omitted because variant matching needs further verification.
Do my files leave my device?
No. Parsing and comparison happen in a browser Web Worker. File contents are held in memory, without server uploads or catalogue storage. Refresh or reset to clear them.
What about currencies and price formats?
No conversion is performed. Map optional currency columns to detect mismatches. Missing currency information produces a warning; cost mode also requires your explicit acknowledgement. Use plain decimals with a dot, without thousands separators or currency symbols. Up to 12 decimal places are supported.
What happens to uncertain matches?
Empty identifiers, duplicate identifiers, invalid prices and mismatched currencies cannot be approved. Products are never matched by title.
How do I preserve leading zeros in Excel?
CSV preserves SKU characters, but spreadsheet programs may infer numbers when you double-click a file. In Excel use Data → From Text/CSV, choose Transform Data, remove any automatic Changed Type step, and set SKU to Text before loading. In other spreadsheet tools disable automatic number conversion or explicitly import SKU as Text. Quotes alone do not force text. Formula-like text is prefixed with an apostrophe for safety; generated negative differences remain numeric.
