What does this validator check?

It checks if your CSV can be properly parsed, flags unescaped quotation marks, and verifies if every single row has the exact same number of columns.

Is my data sent to a server?

No! All validation happens entirely inside your browser. It is perfectly safe for proprietary and sensitive data.

What is the CSV Validator?

A single unescaped quote or an extra comma can completely break a CSV import script, database load, or spreadsheet presentation. Finding the exact row where the error occurred in a massive file is incredibly frustrating.

Our CSV Validator instantly analyzes your spreadsheet data and tells you exactly what is wrong and where to find it.

Validation Checks

Syntax Errors: Detects improperly escaped quotes and malformed delimiter structures.
Column Consistency: Ensures that every row in the file has the exact same number of fields as the header row.
