What is an orphaned record?

An orphaned record is a row in a child table that references a primary key value that does not exist in the parent table.

Can I validate data that is case-sensitive?

Yes, you can toggle the 'Case Sensitive' option to ensure that 'ID-01' and 'id-01' are treated as distinct values.

How do I handle empty cells in my data?

Enable the 'Ignore Empty Values' checkbox to skip null or empty fields during the validation process.

What output formats are supported?

The tool supports Detailed Reports, Summary views, JSON format, and CSV exports for invalid records.

Is there a limit to the number of rows I can validate?

The tool is designed for efficient processing, but performance depends on your browser's memory capacity for very large datasets.
