Many tools and platforms expect CSV input, but TSV files are common in bioinformatics, linguistics, and data exports from Unix-based systems. This converter bridges the gap. Analysts use it to convert tab-delimited exports into CSV for Excel or Google Sheets. Developers use it to normalize TSV data for import into databases or APIs that expect comma-separated input. Since everything runs locally in your browser, it's ideal for sensitive datasets that can't be uploaded to third-party services.
