Public synthetic demo · beta in preparation
Review the changes.
Before the import.
A second look at your next catalog update. Compare a current Shopify product CSV with a proposed update to spot supported price changes, cleared fields and identifiers that cannot be matched.
No signup or payment for the demo. Fixed synthetic files only. Nothing to install.

A review, before your next step
Two files. One clearer picture.
- 01
Choose the baseline
Use the current catalog export from the same store and currency as your proposed update.
- 02
Review the findings
See supported changes and matching blockers. Missing or duplicate identifiers stay visible as an incomplete comparison.
- 03
Keep a report
Export a standalone HTML report, or CSV and JSON findings, with the comparison settings and coverage limitations.
Try a report now. Help test the workflow next.
How to get trial access
The public demo is open immediately. It compares a fixed fictional catalog and update, shows the findings, and offers a standalone sample report. It does not accept your files.
- 01
Check whether it fits
We are looking for a few people who have worked with Shopify product CSVs in the last six months. The volunteer workflow trial uses English instructions and Windows with Chrome or Edge.
- 02
Send a short request
Email your general catalog role, recent CSV experience and browser. Please leave out store names, merchant files, reports, credentials and payment details.
- 03
Arrange a synthetic trial
After confirming fit, we supply the prototype package, synthetic files and task instructions individually. Allow up to 45 minutes. Participation is voluntary and unpaid; no purchase or store access is needed.
Or write to csvchangeguard.support@gmail.com. We aim to reply within two business days. Trial access is arranged individually, not an automatic download. You can stop at any time.
The prototype is not for sale. This demonstration does not grant a commercial licence or access to a paid package. Live sales remain disabled.
Know what is assessed
Useful findings.
Explicit boundaries.
The utility compares a documented subset of Shopify product CSV fields. It uses exact, case-sensitive handle + non-empty SKU pairs; it does not guess matches from row order.
- Price changes and a configurable movement threshold
- Explicitly cleared supported fields
- Supported option and visibility changes
- Missing, duplicate and unmatched identifiers
Absent rows are not predicted deletions. Omitted columns are not treated as explicit blanks. Zero findings is not approval to import.
Your catalog stays with you
No store connection. No CSV uploads.
The downloadable utility reads selected files in your browser and processes them locally. The public demo runs the same comparison engine with fixed synthetic inputs only. Neither uploads catalog files, calls AI services, tracks usage or asks for Shopify credentials.
This website has no file upload or contact form. Cloudflare handles technical request data; consumer Gmail handles support and trial correspondence. Read our website and support privacy notice. Please use synthetic examples and do not send merchant CSVs, reports, passwords or payment details.
This is an independent comparison tool, not a complete Shopify import simulator. Review coverage, keep an appropriate backup and test your actual import workflow separately.
