TSV (tab-separated values) is preferred in bioinformatics, linguistics, and many Unix-based workflows where commas appear inside data values. This converter makes the switch effortless. Data scientists use it to prepare files for tools that expect tab-delimited input. Bioinformaticians use it to convert CSV exports into the TSV format required by genomics pipelines. Developers use it to generate TSV fixtures for testing. Since everything runs locally in your browser, it's safe for sensitive datasets that can't be uploaded to third-party services.
