XLSM is Excel’s macro-enabled spreadsheet format, a powerhouse since Office 2007. It stores data, charts, and VBA macros—scripts that automate tasks like calculations or formatting. It’s a go-to for professionals who need to save time on repetitive processes. But XLSM’s tie to Excel and macro compatibility can limit sharing, especially with open-source tools. Think of it as a fancy gadget—super useful, but it needs the right software to shine.

OTS stands for OpenDocument Template Spreadsheet, a lesser-known gem in the ODF family. Used by LibreOffice and OpenOffice, it’s a template format for creating reusable spreadsheets with predefined formulas, styles, or charts. Unlike ODS, OTS is about consistency—perfect for reports or budgets you need to replicate. It’s open-source, lightweight, and works across platforms, making it ideal for collaborative or free software fans. Picture OTS as a blueprint for spreadsheets, ready to customize.

If data looks off, check Excel’s formatting. These steps ensure your OTS templates are ready to roll.

XLSM to OTS conversions are usually seamless, but glitches happen. Macros missing? OTS doesn’t support VBA, so remove them first. Broken formulas? Replace Excel-specific functions with universal ones. If the file won’t open, verify the XLSM isn’t corrupted. Test the OTS in LibreOffice to spot issues.

Security is crucial for online converters. Runconvert.com deletes your files after conversion, ensuring privacy. Use HTTPS sites for secure uploads.

XLSM and OTS serve different spreadsheet needs. XLSM, Excel’s macro-enabled format, is great for automation but tied to Microsoft. OTS, an open-source template format, is designed for reusable designs in LibreOffice, skipping macros. XLSM is feature-rich but proprietary; OTS is lightweight and universal. Use XLSM for dynamic data, OTS for consistent templates. It’s like a custom-built machine versus a ready-to-use mold.

XLSM and OTS differ technically. XLSM, XML-based, supports VBA macros and complex data but requires Excel. OTS, part of ODF, is a lightweight template format for open-source apps, lacking macro support. XLSM files are larger; OTS files are compact. Both handle data and charts, but OTS is more cross-platform. The chart below compares their technical features.
