How to Use the CSV Validator Tool
✅ Open the CSV Validator and follow along with this tutorial.
Open Tool →Step 1: Upload Your CSV
Click Upload CSV. The tool parses the entire file and runs all validation checks immediately.
Step 2: Review the Validation Summary
The results panel shows each check with a green ✓ (passed) or red ✗ (failed) indicator. The summary shows total rows checked, issues found, and which checks triggered.
Step 3: Inspect Specific Issues
Failed checks expand to show details: row numbers of inconsistent-count rows, list of duplicate headers, etc. This tells you exactly where problems are so you can fix them.
Step 4: Fix the Issues
Based on the issues found:
- Header issues → use the CSV Header Fixer
- Delimiter mismatch → use the CSV Delimiter Converter
- Column count issues → open the file in a text editor or spreadsheet to correct misaligned rows
Privacy reminder: All processing is local. Your file is never uploaded anywhere.
