Understand the problem before changing your file.

Every diagnosis includes the affected record and column, an explanation, and a rule source. Review a before/after diff, accept an eligible fix, or supply a value you know is correct. Changes run through validation again.

What this tool can check

  • Quoted delimiters, record widths, duplicate headers, malformed CSV, and risky spreadsheet formulas.
  • String preservation for identifiers, unknown columns, Unicode, and multiline descriptions.

What still needs your judgment

Golanto does not know your store’s existing catalog, inventory locations, approved taxonomy, or account-specific requirements. It never invents prices, identifiers, inventory, units, or compliance claims. Passing these checks does not guarantee marketplace acceptance.

Use a backup and test a small import first. Shopify update files can clear existing values when supplied fields are empty.
