Frequently Asked Questions

Is converting TXT to XLSX free?

Yes. This TXT → XLSX converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert TXT to XLSX?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my TXT files uploaded to a server?

No. Files never leave your device. The entire TXT → XLSX conversion runs locally in your browser, so your data stays private.

Can I convert multiple TXT files at once?

Yes — batch conversion is supported. Add as many TXT files as you like and convert them to XLSX in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting TXT to XLSX lose quality?

No. XLSX is a lossless format (or used in a lossless mode here), so the original data from your TXT file is preserved bit-for-bit in the converted result.

Does XLSX support transparency from TXT?

Yes. XLSX supports an alpha channel, so any transparent regions of your TXT file will be preserved as transparent in the converted file.

How will the file size change after converting TXT to XLSX?

Both formats use comparable compression, so the XLSX output will be similar in size to your TXT file — typically within 10–20% of each other.
