More about XLSM to ODS (Spreadsheet converter)

What is an XLSM File?

XLSM (Excel Macro-Enabled Workbook) is a file format used by Microsoft Excel that supports macros—automated scripts created to simplify repetitive tasks. These files allow users to embed VBA (Visual Basic for Applications) code, custom functions, and automated processes within a spreadsheet. XLSM files are typically used in Microsoft Excel to perform advanced tasks and automate workflows, offering a high level of flexibility and customization.

However, XLSM files may not be universally supported across all platforms, particularly those that do not use Microsoft Office. As such, converting an XLSM file to a more widely compatible format like ODS (OpenDocument Spreadsheet) can be an effective way to ensure accessibility across various spreadsheet programs.

What is an ODS File?

ODS (OpenDocument Spreadsheet) is an open standard file format used by a range of spreadsheet applications, including LibreOffice Calc and OpenOffice Calc. ODS files store tabular data and support a range of spreadsheet features, such as formulas, cell formatting, and charts. One of the key advantages of the ODS format is that it is based on open standards, making it platform-independent and widely supported by free and open-source software.

Unlike XLSM files, ODS files do not support macros, so the conversion from XLSM to ODS will remove any macros or VBA code present in the original file. However, the data, formulas, and other features of the spreadsheet will remain intact, allowing users to access and manipulate the content in a widely supported format.

Why Convert XLSM to ODS?

Converting an XLSM file to ODS can be beneficial for several reasons:

• Cross-Platform Compatibility: ODS files are compatible with a variety of spreadsheet programs, including open-source applications like LibreOffice and OpenOffice, as well as commercial software like Microsoft Excel. This makes ODS an excellent choice for users who want to share files across different platforms and environments.
• Open Standards: ODS is based on the OpenDocument standard, which is freely available and widely supported by open-source software. This makes ODS a good choice for users who prefer using open-source tools or need to ensure that their files remain accessible in the long term.
• File Size Reduction: XLSM files can be relatively large due to the embedded macros and other advanced features. Converting to ODS can sometimes reduce file size, making it easier to share, store, and work with the data.
• Security: XLSM files contain macros that can sometimes pose security risks, especially if the macros are not properly managed. Converting an XLSM file to ODS removes any embedded macros, making the file safer to share and reducing the risk of running malicious code.

How to Convert XLSM to ODS

There are several ways to convert an XLSM file to ODS, depending on your preferences and the tools you have available. Here are some common methods:

• Using LibreOffice Calc: LibreOffice Calc is a free and open-source spreadsheet program that can easily open XLSM files and save them as ODS files. To convert an XLSM file to ODS using LibreOffice:
  1. Open LibreOffice Calc.
  2. Click on “File” and select “Open” to open the XLSM file.
  3. Once the file is open, click on “File” again and select “Save As.”
  4. In the “Save as type” dropdown, select “OpenDocument Spreadsheet (.ods).”
  5. Click “Save” to convert the file to ODS.
• Using OpenOffice Calc: Similar to LibreOffice Calc, OpenOffice Calc is another free, open-source spreadsheet program that supports both XLSM and ODS formats. The conversion steps are the same as those outlined for LibreOffice Calc.
• Using Microsoft Excel: If you prefer using Microsoft Excel, you can save an XLSM file as an ODS file directly from Excel. Here’s how:
  1. Open the XLSM file in Microsoft Excel.
  2. Click on “File” and select “Save As.”
  3. Choose the location where you want to save the file.
  4. In the “Save as type” dropdown, select “OpenDocument Spreadsheet (.ods).”
  5. Click “Save” to convert the file to ODS.
• Using Online Conversion Tools: There are many online tools that can quickly convert an XLSM file to ODS. These tools are easy to use and typically require you to upload your file, select ODS as the output format, and download the converted file.
• Using Python or Command-Line Tools: For users who need to automate the conversion of XLSM files to ODS, Python libraries like `pandas` or `odfpy` can be used. Here’s an example using `pandas`:

      import pandas as pd
      df = pd.read_excel("file.xlsm", sheet_name="Sheet1")
      df.to_excel("output.ods", engine="odf")
      

  This method is useful for batch processing multiple files or integrating the conversion process into a larger automation workflow.

Step-by-Step Guide to Converting XLSM to ODS Using LibreOffice Calc

If you prefer using LibreOffice Calc to convert your XLSM file to ODS, follow this step-by-step guide:

1. Open LibreOffice Calc on your computer.
2. Click on “File” in the top menu, then select “Open” to open your XLSM file.
3. Once the file is loaded, go to “File” again and choose “Save As.”
4. In the “Save as type” dropdown menu, select “OpenDocument Spreadsheet (.ods).”
5. Choose the location where you want to save the ODS file, then click “Save” to complete the conversion.

Benefits of Converting XLSM to ODS

There are several advantages to converting XLSM files to ODS:

• Cross-Platform Use: ODS files are open and accessible across a wide range of spreadsheet programs, including LibreOffice, OpenOffice, and Google Sheets, making them more versatile than XLSM files, which are primarily designed for Microsoft Excel.
• Free and Open-Source: ODS is an open standard that is supported by many free and open-source applications, ensuring that your files will remain accessible without relying on proprietary software like Microsoft Excel.
• Smaller File Size: XLSM files can be relatively large due to the inclusion of macros and VBA code. Converting to ODS can sometimes result in a smaller file size, making it easier to share and store the data.
• Security: Since ODS files do not support macros, converting an XLSM file to ODS removes any potential security risks associated with embedded macros.

Things to Keep in Mind When Converting XLSM to ODS

Before you convert an XLSM file to ODS, be aware of the following:

• Loss of Macros: Converting an XLSM file to ODS removes any macros or VBA code contained within the file. If you need to preserve the functionality of macros, you may need to explore other formats that support them, such as XLSM or XLSX.
• Data Loss in Complex Features: Any complex features like ActiveX controls, form controls, or certain types of Excel-specific formulas may not work properly in ODS. Ensure that you review the content after conversion to ensure everything is as expected.

Conclusion

Converting an XLSM file to ODS is an excellent way to make your Excel file more accessible across different platforms and software. ODS offers a reliable, open-standard format that works with both free and commercial applications. While you will lose macros and some Excel-specific features, the resulting file will be compatible with a wider range of tools and will be safer to share due to the removal of potentially harmful macros. Use the methods outlined above to easily convert your XLSM files to ODS and enjoy the benefits of a versatile, open-format spreadsheet.
