How to convert ODS to Excel XLSX
- Add your .ods files.
- Excel (.xlsx) is preselected — start the conversion.
- Download your .xlsx workbooks.
.ods (OpenDocument Spreadsheet) is the format of LibreOffice Calc and OpenOffice. It is common in schools, universities, some public offices and among Linux users. But your accountant, bank or client most likely uses Excel and asks for an .xlsx file.
Excel can open .ods files, but some formatting or functions don't come through well, and many business programs, import tools and services like Power BI expect a real .xlsx. Converting before you send avoids surprises: a grade sheet, a budget or a list of registrations arrives exactly as you prepared it.
The conversion is done by LibreOffice, which knows the .ods format inside out: every sheet, formula, number and date format, merged cell and color is carried over. Up to 50 files at once, removed from our servers after 30 minutes.
Tip: after opening the file in Excel, check conditional formatting and charts, which are converted but can look slightly different. Data validation lists, cell comments and frozen panes are kept. If you share the workbook with a team that uses both suites, .xlsx is the safest common format: LibreOffice opens and saves it without trouble, so nobody has to switch software.
Frequently asked questions

Are all sheets converted?
Yes, the .xlsx workbook contains every sheet of the .ods file, in the same order.
Do I need to install anything?
No, everything happens online in your browser, on a computer or a phone.
Is my data safe?
Files are processed in memory, never shared, and deleted automatically after 30 minutes.
