Frequently asked questions
Is my TSV file uploaded?
No. The file is read by your browser and shown on your own device. Nothing is sent to a server, and it is gone when you close the tab.
How do I open a TSV file without installing software?
Drop the .tsv, .tab file on this page. It opens straight away in the CSV & Excel Viewer, on Windows, macOS, Linux, Android and iPhone alike.
What if my TSV file doesn't open?
The viewer checks the file's content, not just its name. If it is damaged or not really a TSV file, you'll see an error or can switch to the hex view to look at the raw bytes.
Can I convert TSV to another format?
Yes. The free file converter turns TSV files into other formats in your browser as well, without uploading them.
