Clean Your CSV Online — Fix Broken CSVs in Seconds

CleanYourCSV.com repairs broken CSVs, removes duplicates, and normalizes data for Shopify imports, email lists, and survey analysis. Free for small files (up to 250 rows) with affordable plans for larger datasets.

Clean CSV for Shopify Imports

Shopify requires CSVs to follow strict formatting rules. If your import fails, it's usually because of extra spaces, broken headers, or invalid price fields. CleanYourCSV.com automatically standardizes headers, fixes product prices, and prepares your data so it imports into Shopify without errors.

Clean CSV for Email Marketing Lists

Email campaigns fail when your CSV contains duplicate or invalid emails. Our tool automatically lowercases emails, removes duplicates, and flags invalid addresses — giving you a clean list ready for Mailchimp, HubSpot, or any email platform.

Normalize Survey CSV Data

Survey results often include inconsistent dates or state names. With CleanYourCSV.com, dates are normalized to YYYY-MM-DD format, and U.S. states are standardized to two-letter codes. Your survey analysis becomes easier, faster, and more accurate.
