Nothing is written until you download. The table shows exactly what each cell becomes, so you can catch a rounding rule or a stray minus sign before it reaches your store.

Charm pricing

The .99 and .95 rules round to the nearest whole unit first, then set the ending. A 10% rise on $18.50 becomes $20.35, which lands on $19.99 or $20.99 depending on which side it falls.

If a specific price point matters, check the preview rather than assuming.

Re-importing to Shopify

Keep the Handle column intact — that is how Shopify matches rows to existing products. Importing with “overwrite existing products” enabled updates them in place rather than creating duplicates.

Export a fresh backup first. This tool cannot undo an import.
