CSV Change Guard

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.

Downloadable browser utility. CSV processing stays on your computer.

A change worth a second lookSynthetic example

desk-lamp / LAMP-001

59.005.90
−90%

A price drop above the selected 30% threshold.
Intentional discount—or a misplaced decimal?

Illustrative report finding. Currency is not inferred.

A review, before your next step

Two files. One clearer picture.

  1. 01

    Choose the baseline

    Use the current catalog export from the same store and currency as your proposed update.

  2. 02

    Review the findings

    See supported changes and matching blockers. Missing or duplicate identifiers stay visible as an incomplete comparison.

  3. 03

    Keep a report

    Export a standalone HTML report, or CSV and JSON findings, with the comparison settings and coverage limitations.

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 utility reads selected files in your browser and processes them locally. It does not upload catalog files, call AI services, track usage or ask for Shopify credentials. Reports are downloaded to your device.

This informational page has no file upload or analytics. Emailing support shares your message with Gmail. 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.
