What is a TSV File?
TSV stands for Tab-Separated Values.
Instead of commas, each column is separated by a tab character.
TSV files are commonly generated by:
PostgreSQL
MySQL
Microsoft Excel
Google Sheets
Scientific datasets
Data export tools
Although TSV is simple, opening it isn't always simple.
Common Problems When Opening TSV Files
Many users run into these issues:
✅ Excel imports all columns into one cell.
✅ The file opens with garbled text because of the wrong encoding.
✅ The dataset is too large to preview comfortably.
✅ You only need to inspect or edit a few rows.
If you've experienced any of these, an online TSV viewer can save a lot of time.
Open TSV Files Like Excel
Instead of opening TSV files as plain text, the viewer displays them in an Excel-like table.
It supports:
Editable cells
Row and column headers
Column resizing
Sorting
Filtering
Keyboard navigation
If you've used Excel before, you'll already know how to use it.
No More Garbled Text
One of the biggest frustrations with TSV files is text encoding.
Many TSV files are not UTF-8.
For example:
Shift_JIS
GBK
Big5
Windows-1252
ISO-8859-1
When opened incorrectly, you may see unreadable characters instead of your data.
This viewer automatically detects the file encoding whenever possible, helping display text correctly without requiring manual conversion.
Edit TSV Files Directly/Online
Sometimes you only need to make a few quick changes.
Instead of importing the file into Excel and saving it again, you can edit the data directly in your browser.
Useful for:
Fixing product data
Cleaning exported datasets
Updating inventory
Reviewing logs
Editing tabular text
Convert TSV to CSV/Excel.xlsx
Need a CSV instead?
After opening the file, you can export it as CSV in just a few clicks.
This is useful when another application only accepts CSV.
Convert TSV to Excel (.xlsx)
Need to send the data to someone using Microsoft Excel?
The viewer can also convert TSV into an Excel workbook (.xlsx), making it easy to share or continue editing in Excel.
