XLS to TSV Converter
Processing entirely on your device — large files may take a moment.
Many research datasets and database dumps ship as TSV; converting to CSV or JSON makes them broadly usable. If your files are still in XLS format, this page is the shortcut: XLS is the classic Excel 97–2003 workbook format, still produced by many banks, ERP systems and export tools.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

Frequently asked questions
Is this XLS to TSV converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
What about special characters and non-English text?
Everything is handled as UTF-8. When you export CSV for Excel, a UTF-8 BOM is included automatically so Chinese, Japanese, Korean and accented characters display correctly on both Windows and macOS.
