How This Works Under the Hood

From Tab-Separated Text to a Real Spreadsheet

TSV is everywhere -- it's what sits on your clipboard when you copy from Excel, Google Sheets, or Numbers. It's what many databases spit out. This tool takes that raw text and builds a proper .xlsx file with headers, rows, and columns all in the right places. Need Markdown instead? Try our TSV to Markdown converter.

Preview Before You Download

Before you download anything, the tool shows you a preview of the first 8 rows along with a row count and column count. I added this because I kept downloading files only to realize I'd copied one column too few. Now you can catch that before hitting download.

Built with SheetJS, Runs Locally

The Excel generation uses SheetJS (also called xlsx.js), an open-source library that runs in your browser. Your data stays on your machine the entire time. No cloud, no server, no data collection. For JSON source data, check out our JSON to Excel converter.

When This Comes in Handy

Turning Database Exports into Spreadsheets

Run a query in DBeaver or psql, copy the tab-separated results, paste here, and you've got an Excel file to send to your team. Way faster than exporting to CSV and then importing into Excel manually.

Making Sense of Log Files

A lot of server logs use tab separation. Paste a chunk of log output here and get an Excel file where you can sort by timestamp, filter by error level, or search for specific request IDs. Much better than reading raw text.

Lab and Research Data

Lab instruments and scientific software often export TSV. If you need to graph the results or run calculations, converting to Excel is the quickest path. Paste it in, download, open in Excel, start charting.

Sharing Data with Non-Technical People

Not everyone knows what a TSV file is or how to open one. But everyone can open an .xlsx. If you have tab-separated data from Linux or Mac tools, convert it to Excel before sharing with teammates on Windows.

Frequently Asked Questions

It reads tab-separated text and creates a real .xlsx Excel file from it. You paste in TSV data (or copy cells from a spreadsheet), and you get a downloadable Excel file. The whole thing runs in your browser using the SheetJS library -- no uploads, no server processing.
Anywhere, really. Copy cells from Excel or Google Sheets and the clipboard already contains TSV. You can also paste from .tsv files, database query results, or any app that exports data as tab-delimited text. If your data comes from a different format, we've got tools for that too.
Paste your TSV into the left side. Click Sample if you want to try it with example data first. A table preview shows up on the right so you can double-check everything looks right. Then click Download Excel to grab the .xlsx file. Simple.
One sheet named Sheet1 with all your data. Row 1 becomes column headers. It opens fine in Excel, Google Sheets, LibreOffice, Numbers -- any spreadsheet app. No macros, no weird formatting. Just a clean data table.
Yes. The Excel file gets built right in your browser using SheetJS (it's open source). Nothing gets uploaded. I don't see your data, nobody does. Safe for internal reports, HR data, financial figures, whatever you need.
Not at all. The tool figures out the widest row and pads the shorter ones with empty cells. So if row 3 has 5 columns but most rows have 7, row 3 gets two blank cells at the end. Your Excel file comes out with a clean, consistent grid.
You can, but Excel's import wizard asks you to pick delimiters, encoding, column types... it's a whole process. And sometimes it guesses wrong and turns your dates into numbers or your zip codes into integers. This tool skips all that and gives you a ready-to-use .xlsx.
Pretty big. The preview only shows the first 8 rows, but the downloaded file includes everything. I've tested it with 10,000+ row datasets without issues. If you hit browser memory limits on very large files, try breaking the data into chunks.
Yep, free forever. No account, no limits. Check out these too: TSV to Markdown, JSON to Excel, CSV to Markdown, and Markdown to Excel.
