FOR SHOPIFY PRODUCT IMPORTS
A small spreadsheet change.
A very different catalog.
See which fields could be cleared and which variants need a second look. Compare your current export with your proposed update before you import.
Files stay in this tab. No store connection. No file upload to our server.
01 / COMPARE YOUR FILES
What are you about to change?
Use product CSVs only. This preview does not check inventory-location files, collections, metafields, live store state or Shopify's complete import behavior. It never changes your file or store.
02 / CHANGE REPORT
Review before importing
A quiet report is not clearance to import. Export a backup, inspect Shopify's import preview and test a small batch. Results describe potential effects; they do not simulate Shopify's importer.
SMALL TOOL. SPECIFIC JOB.
Know what deserves
a second look.
Before → after
Spot populated product fields becoming blank, option changes on uniquely matched SKUs and new product handles in an update.
File structure
Check malformed CSV, missing required headers, ambiguous header aliases and variant-column dependencies. Current and common legacy Shopify headers are supported.
Honest limits
Matching uses handles, option values and unique SKUs in your files. We cannot see your store, apps or import settings. Intentional changes still appear for review.
THE NEXT EDITION
One download. Your files stay yours.
We are testing a $29 one-time offline edition for repeat catalog work. This preview is free. Purchases are not open yet.

Did it catch something useful?
Tell us what you were trying to change, what the report caught or got wrong, and whether you would use it again.
This opens your email app. Please describe the issue without attaching your catalog, customer data, passwords or store access. Support is AI-assisted and limited to this tool. A message does not subscribe you to marketing; a launch update requires your explicit opt-in.
Privacy, scope and source notes
Your selected files are processed in browser memory. This application does not send their contents, filenames or findings to a server and does not retain them after you leave. Downloaded reports stay wherever you save them. The hosting provider may retain standard website access logs; no application analytics, cookies or accounts are added by this tool.
