Frequently Asked Questions
What is CSV diff?
CSV diff is a tool that compares two CSV (Comma-Separated Values) files and highlights the differences between them. It helps you identify added, removed, and modified rows.
How does CSV comparison work?
Our CSV comparison tool parses both CSV files and compares each row. It identifies rows that are new (added), missing (removed), or have different content (modified). The differences are highlighted with colors.
Does it support CSV files with headers?
Yes! If both CSV files have the same header row (first row), the tool will automatically detect it and compare only the data rows while preserving the header context.
Is my data safe?
Yes, all processing is done locally in your browser. Your data never leaves your device. We do not store or transmit any of your files or content.
