CSV validator FAQ

What is a CSV validator?

A CSV validator checks a CSV file for structure and data quality issues such as missing values, duplicate rows, bad dates, type mismatches, and join risks before downstream use.

What data quality issues does GoValidate.ai detect?

GoValidate.ai detects missing values, duplicates, bad dates, type mismatches, format drift, rare values, and join risks that can affect reporting or imports.

Is my uploaded file processed securely?

Yes. CSV validation runs locally in your browser, so raw file contents are not uploaded to a server.
