Compare old and new CSV files to identify added, removed, and changed rows by key column.

Private by design
Private by design: this tool runs in your browser. Your Shopify CSV is processed locally and is not uploaded to our servers. No Shopify login, no Shopify API connection, and no account required.
FAQ
What key columns are recommended?
SKU, Handle, id, product_id, or email are commonly reliable keys.
Can I export the changes?
Yes. Download a simple CSV report of added, removed, and changed rows.
Does this tool do line-by-line visual diffs?
No. V1 focuses on row-level and column-level change summaries.
