TSV (Tab-Separated Values) is one of the most common data exchange formats, produced by spreadsheet applications, database exports, and data analysis tools. This converter instantly transforms TSV text into a fully formatted Excel spreadsheet you can download and open in any spreadsheet application. For converting to Markdown instead, try our TSV to Markdown converter.
Before downloading, you can preview the parsed data directly in the browser. The preview shows the first 8 rows, the number of rows, and the number of columns. This lets you verify the data looks correct before downloading the Excel file.
All Excel generation uses the open-source SheetJS library, running entirely in your browser. No data is ever uploaded to a server. You can use it safely with internal reports, confidential data exports, and sensitive datasets. For JSON data, try our JSON to Excel converter.
A TSV to Excel Converter transforms tab-separated value data into Microsoft Excel (.xlsx) spreadsheet format. TSV files use tab characters to separate columns and newlines to separate rows. This tool reads your TSV data and creates a properly structured Excel spreadsheet with all rows and columns preserved.
TSV data is produced when you copy cells from Excel or Google Sheets — the clipboard content is tab-separated. You can also get TSV from database exports, .tsv files, and applications that export tabular data as text. Simply paste the data into this tool.
Paste your TSV data into the input area on the left, or click Sample to load an example. A preview of the parsed data appears on the right. Click 'Download Excel' to download the .xlsx file. All processing happens in your browser using the SheetJS library.
The generated .xlsx file contains a single sheet (Sheet1) with all your TSV data. The first row is treated as column headers. The file is compatible with Microsoft Excel, Google Sheets, LibreOffice Calc, and any other spreadsheet application.
Yes. All processing happens in your browser using the open-source SheetJS library. Your TSV data never leaves your device and is never sent to any server.
