About TSV files
TSV files are like CSV, but columns are separated by tab characters. They are common in scientific data and database exports because tabs rarely appear inside values.
Open Online shows TSV data in the same grid as CSV, with editing and export.
What you can do here
- Switch between worksheets with tabs
- Scroll large tables smoothly, with row numbers and column letters
- Search all cells and jump between matches
- Click a cell to see its full value
- See sheet sizes, workbook properties and detected column headers
Limitations
- Formulas are shown as their last saved results.
- Charts, images, conditional formatting and cell colours are not displayed.
Privacy
The file is read by your browser and stays on your device. Open Online has no server that could receive it, and nothing is stored once you close the tab. Privacy policy
Common questions
Can I save it as CSV?
Saving keeps tabs as separators. For CSV, Excel or ODS, aintob.com can convert TSV files.
Are quotes handled?
Yes. Quoted values with tabs or line breaks inside them are parsed correctly.
