What is OTS?
OTS (OpenDocument Spreadsheet) is a file format used for spreadsheets, primarily associated with OpenOffice and LibreOffice applications. It allows users to create, edit, and share spreadsheet documents in an open-source format, enabling compatibility across various software platforms. OTS is particularly useful for users seeking alternatives to proprietary formats like Excel, providing a free and flexible option for data handling.
Loss of Formatting
When converting Excel files to OTS, the intricate formatting such as cell styles, fonts, and colors may not transfer accurately, leading to a loss of visual appeal and readability.
Functionality Limitations
Certain Excel functions and formulas may not be supported in the OTS format, resulting in errors or missing calculations that can affect the spreadsheet's functionality.
Compatibility Problems
Not all programs that support OTS can handle advanced features found in Excel, which can lead to compatibility issues when sharing or collaborating on the documents.
Data Integrity Issues
During the conversion process, some data types (such as dates or special characters) may not be interpreted correctly, risking data integrity and potentially corrupting the spreadsheet.
What are the differences between XLSX and XLSM?
File Extension
XLSX is the standard file format for Excel workbooks that do not contain macros, while XLSM is the format used for workbooks that include macros.
Macro Support
XLSX files cannot store macros, making them safer for users who want to avoid running potentially harmful code. In contrast, XLSM files can harbor macros, allowing for automated tasks and advanced functionalities.
File Size
Generally, XLSM files may have a larger file size compared to XLSX files because they store macro information in addition to regular data, which can increase complexity.
Processing Speed
Workbooks saved in the XLSX format tend to open and process faster than XLSM files since they do not have to load any macro-enabled content, possibly improving performance for users not utilizing macros.
