Private by default. Your Shopify product CSV data stays in this browser session. The export applies only safe deterministic changes and leaves manual-review items in the findings list.

Shopify product imports depend on exact header names. This page highlights header whitespace, casing drift, aliases, unknown columns, and missing required fields before row data is reviewed.

Import blockers

Common causes this scan checks

  • Header cells include leading or trailing spaces that are hard to see.
  • Column names use supplier wording instead of Shopify product CSV names.
  • Casing and punctuation changed during manual spreadsheet edits.
  • The file has duplicate, blank, or unknown headers mixed with real product data.

Workflow

How to use the cleaned CSV

  1. Scan the first row and review every invalid or unknown header.
  2. Apply safe header trimming and common alias normalization.
  3. Map or remove unknown supplier columns manually before import.
  4. Rerun validation after header cleanup to reveal row-level issues.

Auto-fix policy

What the export can safely change

  • Trim leading and trailing header whitespace.
  • Correct common case and spacing variations.
  • Mark unknown columns for removal or mapping.
  • Preserve cell data while replacing the header row.

FAQ

Shopify CSV questions

Why are Shopify CSV headers so strict?

The importer maps product data by header name. Small differences can prevent Shopify from reading the intended column.

Will the fixer delete unknown columns?

No. Unknown columns are flagged so you can decide whether to map, remove, or keep them outside the import.

Can header fixes change product data?

Safe header fixes only adjust the column names. Product row values are preserved unless you apply separate row-level fixes.
