TSV files — tab-separated values — are common in bioinformatics, genomics, database exports, and scientific research. Large CSV Viewer automatically detects the tab delimiter in your file and opens it instantly, giving you the same full-featured viewer you'd get with a standard CSV.

How it works

  1. Upload your TSV file. Drag your .tsv or .txt tab-separated file onto the viewer. The tab delimiter is detected automatically — your data appears in a clean table immediately.
  2. Explore your data. Sort any column, apply per-column filters, use the global search bar, or enable regex mode for pattern matching across all columns.
  3. Export your results. Download your data or filtered subset as CSV, JSON, or Excel from the File menu. No row limits on export.
