About TSV
A TSV file holds a table as plain text, one row on each line, its values split by tab characters. Values rarely hold a tab, so most TSV files need no quotes at all, which makes them simple to write and to read.
Databases and data tools export TSV, and copying cells from a spreadsheet gives it too, with a tab between cells and a line break between rows. Science uses it a lot: genome annotations, word lists and many public datasets come as TSV.
Filepeek reads it in pieces as you scroll and counts its rows in the background, so a TSV of several gigabytes opens at once. Values in quotes are read the way spreadsheets write them, and the encoding can be picked by hand.

Questions
How do I open a TSV file?
Drop it on this page or choose Peek a TSV. It opens at once as a table, its header pinned to the top, with nothing to install.
What is the difference between TSV and CSV?
Only the character between values: a tab in TSV, a comma in CSV. Commas are common inside values, so CSV needs quotes much more often. Filepeek opens both, and saves either one as the other.
Can I copy cells into a spreadsheet?
Yes. Select cells with the mouse or the arrow keys and press Ctrl C, or ⌘ C on a Mac. They are copied with tabs between them, which every spreadsheet pastes as cells.
Can I save it as Excel?
Yes. Choose Export, then Save as Excel, CSV, JSON, JSON Lines or Parquet, with every row or only the rows you sorted and filtered.
Is my file uploaded?
No. The table opens inside your browser and never leaves your device.
