ONE EDIT. TWO FILES. A CLEARER CHECK.
Did your price increase
change anything else?
Compare an untouched, supported Shopify product CSV with its edited copy. Check every variant’s ordinary Price against your chosen increase and flag unexpected changes.
No store login. No catalog upload. No import required.
THE CHECKED RULE
Ordinary Price + your percentage.
Everything else unchanged.
Choose 0–100%, with up to two decimal places. Expected prices round to cents using HALF UP. Default: 7%.
Select two CSVs
Use your untouched original and the edited copy. Files stay on your device; the checker reads them in your browser.
Review the differences
Look for unexpected edits or cleared fields, unmatched variants and unsupported identities. Unsupported results need review, not a reassuring match.
Keep a local report
Save the text report for your own records, then clear the selected files. The checker never changes your source files.
A comparison, not an import guarantee
Match only means these supplied files follow the checked rule within the supported scope. It does not establish export authenticity, compare against your live store, predict an import outcome or make importing safe.
Supported scope: the reviewed current-native header format with URL handle, Title, Option1 name, Option1 value and Price. UTF-8, comma-separated; up to 2 MiB, 5,000 records and 100 columns per file. Unknown headers are unsupported.
No legacy-header conversion, linked options, unit-price calculations, decreases, repairs or selective price updates. Compare-at prices, market prices, costs and other supported fields must remain unchanged. Variant identity uses handle and option names/values, not SKU alone.
