ODS and XLSX: two formats for the same spreadsheet
ODS is the OpenDocument Spreadsheet format used by LibreOffice Calc, OpenOffice and several government and education systems. XLSX is Microsoft Excel's format. Both are ZIP archives of XML files describing sheets, rows and cells, but they use different schemas, so a colleague, client or upload portal that expects Excel will often refuse an .ods file outright.
Converting means reading the OpenDocument content, rebuilding each sheet as a grid of values, and writing it back out in the target format. This tool reads the .ods file's content.xml directly, shows you the sheet as an editable table, and then writes .xlsx, legacy .xls, CSV, or a cleaned-up .ods using the SheetJS library. Cell values carry over; complex formatting, charts and macros generally do not, because the two applications model them differently.
Why we built this tool
The usual reason is simple compatibility: a form, a finance system or a colleague only accepts Excel, and you work in LibreOffice. Others need a quick CSV for an import, or want to drop a few rows before sending a sheet on.
Spreadsheets tend to hold the sensitive numbers — payroll, budgets, customer lists, grades. Uploading one to a converter hands all of it to a stranger. Here the file is unzipped and converted in your browser, the editor works on your own device, and the converted file is written straight to your downloads.
Tips and common mistakes
- Choose .xlsx unless someone specifically needs .xls; the legacy format has row and column limits and weaker compatibility.
- Pick the right sheet from the sheet selector before editing — each sheet is converted separately.
- CSV keeps only the values of one sheet, with no formatting or formulas; use it for imports, not for sharing a finished workbook.
- Open the converted file once in Excel before sending it on, especially if the original used merged cells or heavy formatting.
Quick start: using ODS to Excel Converter
- Drop an .ods file onto the page or click to choose one.
- Select the sheet you want and review its rows in the editor.
- Edit cells, delete rows you do not need, or add rows — Undo and Reset are there if you change your mind.
- Choose the output format: .xlsx, .xls, .csv or .ods.
- Convert and download the file.
Working with the data elsewhere? CSV to JSON turns an exported sheet into JSON, and JSON to CSV goes the other way.
Why this tool
ODF (OpenDocument Format) is the open standard used by LibreOffice and OpenOffice. While it's great for open-source workflows, many organizations still prefer Microsoft Excel formats. This tool bridges that gap — and goes further by letting you edit your data before converting.

Frequently asked questions
Will formulas and formatting be kept?
Cell values are converted reliably. Formatting, charts and macros are modelled differently in OpenDocument and Excel, so complex styling may not carry over and is worth checking after conversion.
Can I convert to CSV instead of Excel?
Yes. The output can be .xlsx, legacy .xls, .csv, or .ods again after editing.
Is my spreadsheet uploaded?
No. The .ods file is read and converted entirely in your browser, and the result is saved straight to your device.
