About the Excel to ODS Converter
Need to turn a XLSX file into ODS? This free converter changes XLSX spreadsheets into ODS in a few seconds, right in your browser. People usually convert because XLSX needs a spreadsheet app and is awkward to load into databases or code, while ODS gives you a LibreOffice Calc spreadsheet. ODS files open in LibreOffice Calc, OpenOffice, Excel, Google Sheets and Collabora.
Spreadsheets are read and written with SheetJS, the open-source spreadsheet engine used by thousands of data apps, so every sheet, row and value is handled accurately. Because everything happens on your own device, your spreadsheets are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: every sheet in the workbook is converted; formulas are exported as their calculated values, while text such as PIN codes and phone numbers with leading zeros stays intact.
How to use the Excel to ODS Converter
- Click "Choose files" or drag your XLSX spreadsheets onto the box. You can add several at once.
- Choose whether to convert all sheets or only the first one.
- Press "Convert to ODS". The conversion runs on your device and shows its progress.
- Download each ODS file, or use "Download all (ZIP)" when you converted several.
- Open the result in LibreOffice Calc or OpenOffice to check it; your original XLSX is never changed.
Tips & benchmarks
- All sheets are preserved and the file opens directly in LibreOffice Calc and Excel.
- Merged cells are unmerged and their value is kept in the first cell, which keeps the data easy to filter and import.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the ODS to a website or government portal.
Frequently asked questions
How do I convert XLSX to ODS?
Click "Choose files", select your XLSX spreadsheets, adjust the options if you want, and press "Convert to ODS". The ODS downloads immediately; with several files you can download everything as one ZIP.
Is this XLSX to ODS converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your spreadsheets never leave your phone or computer and nothing is stored on News Appite's servers.
Are formulas, formatting and all sheets kept?
Every sheet is converted (or only the first, if you choose). Formulas are exported as their current values, and cell colours and fonts are not carried over because formats such as CSV, JSON and SQL cannot store them.

What is the difference between XLSX and ODS?
XLSX (Microsoft Excel Workbook (Office Open XML)) is a spreadsheet workbook best suited to working with data in Excel, Google Sheets and accounting or GST software. ODS (OpenDocument Spreadsheet) is a open-standard spreadsheet best suited to LibreOffice Calc users and open, vendor-neutral data archiving.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
