How to convert TSV to XLSX
- Add your .TSV file - drop it in the box above or click to browse.
- Convert it to .XLSX in a few seconds.
- Download your new .XLSX file.
What to expect
- Encoding is the biggest risk: if the TSV contains accented or non-Latin characters, import via the spreadsheet's text wizard and select UTF-8 - double-clicking on Windows may guess the wrong encoding and produce garbled text.
- Cells starting with
=,+,-, or@may be treated as formulas when the workbook opens; only dismiss the security warning for files from trusted sources. - Excel's
.xlsxformat caps each sheet at 1,048,576 rows - a TSV larger than that will be silently truncated, so split very large files before importing.
Frequently asked questions
Does Excel open TSV files directly?
Yes - Excel recognises the
.tsv extension and splits columns on tabs automatically. Use Data > From Text/CSV rather than double-clicking for full control over encoding.Why do my characters look garbled after opening the TSV in Excel?
The file is UTF-8 but Excel opened it using the wrong encoding. Re-import via Data > From Text/CSV and select UTF-8 as the file origin.
Is any data lost when converting TSV to XLSX?
No values are lost if encoding is handled correctly on import. TSV holds only raw values, so there is nothing to strip - formatting and formulas can be added to the workbook afterwards.
Can I convert TSV to XLSX without installing software?
Yes - use the free converter on this page, or import the file into Google Sheets and download it as Microsoft Excel (
.xlsx).
