What "cleaning" a supplier CSV actually fixes
Exports from supplier platforms often carry inconsistent whitespace, empty tracking columns, and prices stored as text with currency symbols attached — all of which cause failed or garbled imports into Shopify. This tool trims every text field, strips fully empty columns, and normalizes any column that looks like a price into a plain two-decimal number.
Step-by-step usage guide
- Export your product list from your supplier as a CSV file.
- Upload it above — the tool reads it locally and shows a quick summary of rows and columns.
- Click Download cleaned CSV to save the processed file, then import it into Shopify via Products → Import.
Frequently asked questions
Does this map columns to Shopify's exact import format?
No — it cleans formatting issues (whitespace, empty columns, price formatting) but doesn't rename columns to Shopify's schema. You may still need to rename headers like "Title" or "Variant Price" to match Shopify's import template.
Is my file uploaded anywhere?
No — parsing happens with a client-side JavaScript library in your browser tab. The file never leaves your device.
