Frequently Asked Questions (FAQ)

What does this CSV Whitespace Trimmer do?
This tool removes leading and trailing whitespace (spaces, tabs) from CSV cell values. It helps clean up messy data exports where values have unwanted padding. You can also use our CSV Viewer to preview your data before trimming.
Can I trim only specific columns?
Yes! You can choose to trim all columns, or specify columns by their number (e.g., "1", "2-5", "3, 8") or by their header names. If your CSV has duplicate header names, you can enable the option to trim all matching columns.
What are the left-trim and right-trim options?
Left-trim removes whitespace from the beginning of cell values, while right-trim removes whitespace from the end. By default, both are enabled to fully clean your data, but you can disable either for specific use cases.
How do comments and empty lines get handled?
Enable "Remove Comments" to delete lines that start with a specific character (default: #). Enable "Remove Empty Lines" to strip out blank rows. These options help produce cleaner output data. For more data formatting, try our CSV Delimiter Converter.
Is my data secure?
Absolutely! All processing happens entirely in your browser. Your CSV data is never uploaded to any server, ensuring complete privacy and security.
