Frequently Asked Questions
What is the difference between CSV and TSV files?
CSV uses commas (,) as delimiters, whereas TSV uses tabs (\t). TSV is especially popular in genomics, bioinformatics, and log processing because data fields frequently contain commas.
Can I convert my TSV file to Excel or CSV?
Yes! After dropping your TSV file, you can export it to formatted Microsoft Excel (.xlsx), standard CSV, or Apache Parquet with one click.
How large of a TSV file can I open?
Because parsing occurs client-side in WebAssembly, you can comfortably open TSV files with hundreds of thousands of rows depending on your device RAM.
