Are my XLSX files uploaded anywhere?

No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and watch that nothing is sent while the file converts.

Is converting XLSX to TSV free?

Yes, without a limit on how many files you convert and with no watermark on the result. Files up to 100 MB are covered by the free plan.

Does converting XLSX to TSV lose quality?

No. TSV stores the same content without discarding anything, so the result is identical in quality to the original.

Do I need to install anything to open TSV files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the TSV afterwards needs whatever software normally handles Tab-Separated Values on your device.
