My TSV TSV editor

My TSV
— Edit TSV with ease

No signup. Free. Paste or open a file.
Fix cells in a table, then download in the encoding you need.

Stays local

TSV never leaves your browser. Nothing is uploaded.

Edit in a grid

Click a cell and fix it — lighter than wrestling Excel.

Encodings

Save as UTF-8, UTF-8 BOM, or Shift-JIS for Excel.

Edit TSV

My TSV is a free browser tool for TSV files that are awkward in Excel. Open a file or paste text, edit cells in a spreadsheet-like view, then download as UTF-8, UTF-8 with BOM, or Shift-JIS. History stays in IndexedDB on your device — your TSV is never uploaded to a server. Useful for cleaning exports, fixing headers, and preparing files for Excel on Windows.
