Checks cover selected CSV rules, not every store setting. Repeated product handles and blank variant fields are preserved. Review all changes and Shopify’s import preview before importing.

Change log
Only the changes below are included. The original file on your device stays unchanged.
CSV exports preserve text, including leading zeros and formula-like values. If opening in a spreadsheet, import columns as text rather than enabling formulas.
SMALL CHECKS. USEFUL SIGNALS.
Your spreadsheet
deserves a co-pilot.
Find the field. Keep the context.
Get row numbers for price, boolean, option and identifier checks. Edit a flagged value in place, then run the checks again.
Fix only what you can see.
Optional whitespace fixes come with a before-and-after log. Descriptions, SKUs, barcodes and variant groups aren’t rewritten.

A useful second look.
At your own pace.
Check selected CSV rules, review each change and keep control of your original file.
Small-file exports
Checks, manual edits, conservative fixes and complete CSV/report exports for files up to 100 data rows.
Larger-file review
Files within the checker limits can still be reviewed. Larger exports are not available in this preview. Rows are never silently truncated.
No account, store connection or subscription is required. This is an independent personal utility.
BEFORE YOU START
Does this guarantee that Shopify will accept my file?
No. The preview checks selected field and format rules. Store settings, taxonomy, remote images and existing products can affect imports. Keep a backup and review Shopify’s own import preview.
Will it remove repeated product handles?
No. Repeated handles can describe variants and extra images. Row order and empty cells are preserved. You decide which findings need a manual change.
What happens to my data?
Parsing, checks, edits and downloads happen in your browser. Your CSV is not uploaded. See the privacy notice for ordinary website connection information.
What can I export?
Complete CSV and issue-report exports are free for files with up to 100 data rows. Larger exports are not available yet. The preview never downloads a silently truncated file.
