About the TSV to Excel Converter
This TSV to XLSX converter turns data files from TSV into XLSX without installing software or uploading anything. It solves a common problem: fewer tools import TSV than CSV or Excel. Converting to XLSX gives you an Excel workbook, ideal for working with data in Excel, Google Sheets and accounting or GST software.
Spreadsheets are read and written with SheetJS, the open-source spreadsheet engine used by thousands of data apps, so every sheet, row and value is handled accurately. Because everything happens on your own device, your data files are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: the delimiter and text encoding are detected automatically; formulas are exported as their calculated values, while text such as PIN codes and phone numbers with leading zeros stays intact.
How to use the TSV to Excel Converter
- Click "Choose files" or drag your TSV data files onto the box. You can add several at once.
- Choose whether to convert all sheets or only the first one.
- Press "Convert to XLSX". The conversion runs on your device and shows its progress.
- Download each XLSX file, or use "Download all (ZIP)" when you converted several.
- Open the result in Microsoft Excel or Google Sheets to check it; your original TSV is never changed.
Tips & benchmarks
- Every sheet is kept and numbers stay numeric, so SUM and sorting work straight away in Excel.
- Merged cells are unmerged and their value is kept in the first cell, which keeps the data easy to filter and import.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the XLSX to a website or government portal.

XLSX (Microsoft Excel Workbook (Office Open XML)) is a spreadsheet workbook best suited to working with data in Excel, Google Sheets and accounting or GST software.

There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.

What is a TSV file?
TSV is like CSV but separates columns with tab characters. Because tabs rarely appear inside values, TSV avoids most quoting problems and pastes cleanly into Excel and Google Sheets.
What is a XLSX file?
XLSX has been Excel's default format since 2007. One workbook can hold many sheets, formulas, number formats and up to 1,048,576 rows by 16,384 columns per sheet.
