Browser-local Shopify CSV preflight

Shopify CSV Import Checker

Check a Shopify product CSV before import for common product data issues: missing titles, blank handles, duplicate SKUs, variant rows, invalid prices, image source gaps, option values, product categories, and barcodes. The CSV is read in your browser and is not sent to Polenest servers.

This tool is not a Shopify app and does not guarantee import success. It is a private CSV preflight step before you use Shopify's own product CSV import workflow.

Shopify import errors this flow is built around

Paste the import preview message into the report box and load the CSV. The checker uses the report first, then falls back to local CSV rules when Shopify does not identify a specific row or column.

"abc" is not a valid price
Title must be specified
File URL is invalidImage URL is invalid
Unclosed quoted field in line 2.
Handle is too long (maximum is 255 characters)
Line is invalid (No details)

How this differs from a generic CSV tool

A generic file converter cannot tell you whether Shopify-oriented product rows are missing expected import fields. This checker maps commerce fields first, then shows the source column used for each export column before creating a local review or import CSV.

Official reference

Shopify maintains its own product CSV import documentation. Use this checker as a local cleanup step, then confirm final import behavior against Shopify's product CSV documentation.
