How It Works
The CSV Date Column Validator works by analyzing the dates in the column you select. It checks each entry to ensure it’s a valid date format (like YYYY-MM-DD or MM/DD/YYYY). If a date doesn’t pass the test, it gets flagged as invalid, and the tool highlights it for you. Here’s the simple formula it follows:
Step 1: Upload your CSV file.
Step 2: Select the column containing dates.
Step 3: Click Validate.
Step 4: Review the highlighted invalid dates.
Step 5: Download the corrected file if needed.
