More about XLSM to XLS (Spreadsheet converter)

What is an XLSM File?

XLSM (Excel Macro-Enabled Workbook) is a specialized file format used by Microsoft Excel to store spreadsheets with embedded macros. These macros are created using Visual Basic for Applications (VBA), allowing users to automate tasks and enhance the functionality of their Excel workbooks. XLSM files are widely used in business environments where automation is crucial for efficiency and productivity.

However, XLSM files are not compatible with all spreadsheet programs, especially those that do not support macros. For users who need to work with a simpler version of their file that retains the data and structure but without macros, converting an XLSM file to XLS (Excel Spreadsheet) can be a practical solution.

What is an XLS File?

XLS (Excel Spreadsheet) is an older, binary file format used by Microsoft Excel to store spreadsheets. Unlike XLSM, XLS files do not support macros, so any automated scripts or embedded VBA code will not function in an XLS file. However, the XLS format still retains the basic functionality of a spreadsheet, including data, formulas, and cell formatting.

Because XLS is an older file format, it is widely compatible with various versions of Microsoft Excel and some other spreadsheet applications. While the XLS format does not support advanced features like macros, it remains a reliable choice for users who need a simpler, broadly supported format for their Excel files.

Why Convert XLSM to XLS?

There are several reasons why you might want to convert an XLSM file to XLS:

• Compatibility: XLS files are compatible with older versions of Microsoft Excel (prior to Excel 2007) and other spreadsheet programs that may not support macros. Converting an XLSM file to XLS ensures that the spreadsheet can be opened and used across different platforms and software versions.
• Remove Macros for Security: Macros in XLSM files can sometimes pose a security risk, as they may contain harmful code. Converting to XLS removes any macros, making the file safer to share, particularly in environments with strict security policies.
• Simplification: If you no longer need the macros and prefer a simpler version of the file that only contains data and basic features, converting an XLSM file to XLS can streamline your workflow.
• File Size Reduction: XLSM files, due to the embedded macros, can be relatively large. Converting them to XLS files may reduce file size, making it easier to share and store the file.

How to Convert XLSM to XLS

Converting an XLSM file to XLS can be done in a few simple steps using Microsoft Excel or other tools. Below are the most common methods for performing this conversion:

• Using Microsoft Excel: The most straightforward way to convert an XLSM file to XLS is by using Microsoft Excel. Here’s how you can do it:
  1. Open the XLSM file in Microsoft Excel.
  2. Click on “File” in the top-left corner of the screen.
  3. Select “Save As” from the menu.
  4. Choose the location where you want to save the file.
  5. In the “Save as type” dropdown, select “Excel 97-2003 Workbook (*.xls).”
  6. Click “Save” to complete the conversion. This will save your XLSM file as an XLS file, removing any macros in the process.
• Using LibreOffice Calc: If you don’t have access to Microsoft Excel, you can use LibreOffice Calc, a free and open-source alternative. To convert an XLSM file to XLS using LibreOffice Calc:
  1. Open the XLSM file in LibreOffice Calc.
  2. Click on “File” in the menu bar and select “Save As.”
  3. Choose “Microsoft Excel 97-2003 (.xls)” as the file format.
  4. Click “Save” to convert the file to XLS.
• Using Online Conversion Tools: Several online tools allow for quick and easy conversion of XLSM to XLS. To use these tools, simply upload your XLSM file, select XLS as the desired output format, and download the converted file. However, be cautious when uploading sensitive information to online platforms, as they may not guarantee the security of your data.
• Using Python: If you need to automate the conversion process or handle multiple files at once, Python libraries such as `pandas` can be used to convert XLSM to XLS programmatically. Here’s an example using Python:

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

  This code will load the data from the XLSM file and save it as an XLS file, omitting the macros in the process.

Step-by-Step Guide to Converting XLSM to XLS Using Microsoft Excel

If you prefer to convert the file using Microsoft Excel, follow these simple steps:

1. Launch Microsoft Excel and open the XLSM file you want to convert.
2. Click on “File” in the top-left corner.
3. From the menu, choose “Save As.”
4. Select the location where you’d like to save the new file.
5. In the “Save as type” dropdown, select “Excel 97-2003 Workbook (*.xls).”
6. Click “Save” to finish the conversion. The new file will be saved as an XLS file with the macros removed.

Benefits of Converting XLSM to XLS

There are many reasons to convert an XLSM file to XLS:

• Broader Compatibility: XLS files can be opened by all versions of Microsoft Excel, including older versions that do not support macros. This ensures that the file is accessible to a wider audience.
• Increased Security: By removing the macros from the file, you eliminate any potential security risks associated with VBA code. This is especially important when sharing files with colleagues or clients who may not be comfortable working with macro-enabled files.
• Smaller File Size: XLS files are typically smaller in size than XLSM files, which can be beneficial for sharing or storing files with limited space.

Things to Keep in Mind When Converting XLSM to XLS

Before you convert your XLSM file to XLS, be sure to consider the following:

• Loss of Macros: The primary difference between XLSM and XLS files is the inclusion of macros. Converting an XLSM file to XLS will remove any macros or VBA code from the file. If the macros are essential for your workflow, consider keeping the XLSM format or using a different file format that supports macros.
• Potential Loss of Advanced Features: Some advanced features that are available in XLSM files may not function properly in the XLS format. These features include certain formulas or custom Excel functions that are macro-dependent.

Conclusion

Converting an XLSM file to XLS can be an excellent way to simplify your workbook, remove macros for security reasons, and ensure compatibility with older versions of Excel. While you lose the automation and custom functions provided by macros, the data, formulas, and formatting will remain intact. Whether you use Microsoft Excel, LibreOffice Calc, or an online converter, the process is quick and easy. Just be sure to review the resulting XLS file to ensure that all necessary features are preserved and that the file meets your needs.
