Convert ODS to Excel
Ethical Tube's free ODS to Excel converter turns ODS spreadsheets into Excel (XLSX), Microsoft Excel's spreadsheet format, using LibreOffice, the open-source office suite. It runs entirely in your browser, so your spreadsheets are never uploaded, and it's free with no sign-up or watermark. The first conversion downloads the LibreOffice engine (77 MB) once, and it's cached after that.
Files are converted on your device and never uploaded.

The formats
ODS and Excel at a glance
What is an ODS file?
ODS is the OpenDocument spreadsheet format, the default in LibreOffice Calc and an open ISO standard. Excel and Google Sheets open it, though some formatting and advanced formulas may not carry over exactly. It opens in LibreOffice Calc, Apache OpenOffice, Microsoft Excel, and Google Sheets.
What is an Excel file?
XLSX is the workbook format Microsoft Excel has used since 2007. A workbook can hold several sheets with formulas, formatting, charts, and filters, and it's the standard way spreadsheets are shared at work. It opens in Microsoft Excel, Google Sheets, Apple Numbers, LibreOffice Calc, and WPS Office.
Good to know
What changes when you convert ODS to Excel
- Text, formatting, tables, and images carry over to Excel.
- Moving between OpenDocument and Microsoft formats can shift complex layouts, so check documents with heavy formatting.
- The first conversion downloads LibreOffice compiled to WebAssembly (77 MB). It's cached, so later visits start quickly.
- Chinese, Japanese, and Korean text may appear in a fallback font.
- Password-protected documents can't be converted.
- It works best on a computer, because LibreOffice needs a lot of memory.
FAQ
Questions, answered
Is this ODS to Excel converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with LibreOffice compiled to WebAssembly, so your files never leave your device. Once the page and the engine have loaded, it even works offline.
Why is there a download the first time?
The conversion uses LibreOffice, the open-source office suite, compiled to run inside your browser. It's about 77 MB, downloads once from Ethical Tube's own server, and is cached for next time. Your documents are never uploaded.
Can I convert several ODS files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each Excel file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
It works in Chrome, Edge, Firefox, and Safari, but it's built for computers. LibreOffice needs about 1 GB of memory, which many phones can't spare.
What can open an Excel file?
Microsoft Excel, Google Sheets, Apple Numbers, LibreOffice Calc, and WPS Office.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle documents with hundreds of pages.
