About the XLS to ODS Converter
This XLS to ODS converter turns spreadsheets from XLS into ODS without installing software or uploading anything. It solves a common problem: XLS is a legacy format limited to 65,536 rows. Converting to ODS gives you a LibreOffice Calc spreadsheet, ideal for LibreOffice Calc users and open, vendor-neutral data archiving.
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 XLS to ODS Converter
- Click "Choose files" or drag your XLS 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 XLS 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 XLS to ODS?
Click "Choose files", select your XLS 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 XLS 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.
Can I convert several XLS files at once?
Yes. Add as many XLS files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed.
What is the difference between XLS and ODS?
XLS (Microsoft Excel 97–2003 Workbook) is a legacy binary spreadsheet best suited to older Excel versions, legacy ERP and bank systems and portals that only accept .xls. 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.
How do I convert XLS to ODS in Excel?
In Excel choose File → Save As and pick the format. This converter does it without Excel installed.
