TSV stands for Tab-Separated Values. It is a plain text format where each record occupies one line and each field within the record is separated by a tab character. It is similar to CSV but uses tabs instead of commas, which avoids issues when field values contain commas.

Is my data sent to a server?

No. All parsing and rendering is performed entirely in your browser using JavaScript. Your data never leaves your device.

What happens if my data has no header row?

The first row is always used as column headers. If your data has no header row, the first data row will be treated as headers. You can prepend a header row manually before pasting.

Yes. Click any column header to sort the table by that column. Click again to reverse the sort order. An arrow indicator shows the current sort direction.

How many rows can this handle?

The viewer works well for datasets up to several thousand rows. Very large datasets (tens of thousands of rows) may render slowly depending on your device, but there is no hard limit.

Can I upload a .tsv file?

Yes. Click the file upload button to open a .tsv or .txt file from your device. The file content is read locally by your browser and never uploaded anywhere.
