Convert XLS to OTS

Understanding xls and ots file formats

XLS is the proprietary spreadsheet file format used by Microsoft Excel, primarily in versions prior to Excel 2007. It stores data in tables, formulas, charts, and macros. OTS stands for OpenDocument Spreadsheet Template, a format used by LibreOffice Calc and Apache OpenOffice Calc for spreadsheet templates. OTS files are based on the OpenDocument standard and are ideal for creating reusable spreadsheet layouts.

Why convert xls to ots?

Converting XLS to OTS is useful when you want to use an existing Excel spreadsheet as a template in LibreOffice or OpenOffice. This allows you to standardize spreadsheet creation across different platforms and benefit from the open-source OpenDocument format.

How to convert xls to ots

The most reliable way to convert XLS to OTS is by using LibreOffice Calc, a free and open-source office suite that supports both formats natively. Here’s how you can do it:

1. Open LibreOffice Calc.
2. Go to File → Open and select your XLS file.
3. Once the file is open, go to File → Save As.
4. In the Save as type dropdown, select ODF Spreadsheet Template (*.ots).
5. Choose your destination folder and click Save.

Best software for xls to ots conversion

• LibreOffice Calc – Free, cross-platform, and supports both XLS and OTS formats.
• Apache OpenOffice Calc – Another open-source alternative that can open XLS files and save as OTS.
• Online converters – Some online tools like Zamzar or CloudConvert may support this conversion, but desktop software is recommended for better formatting preservation and privacy.

Tips for successful conversion

• Check your spreadsheet for complex macros or formulas, as some features may not transfer perfectly between formats.
• After conversion, review the OTS template in LibreOffice or OpenOffice to ensure all formatting and data are intact.
