More about XLSM to XLSX (Spreadsheet converter)

What is an XLSM File?

An XLSM file is a Microsoft Excel file format that supports macros, which are automated scripts written using Visual Basic for Applications (VBA). These macros allow users to automate repetitive tasks, create custom functions, and perform complex calculations within Excel. XLSM files are commonly used in environments where automation is crucial, such as in business, finance, and data analysis.

While XLSM files offer powerful automation features, they are not as widely supported as the simpler XLSX format, particularly by software that does not support macros. If you no longer need the macros in your workbook and want a more compatible version of your file, converting from XLSM to XLSX can be a practical solution.

What is an XLSX File?

XLSX is the default file format for Microsoft Excel workbooks since the release of Excel 2007. Unlike XLSM, XLSX files do not support macros or any embedded Visual Basic for Applications (VBA) code. XLSX files are designed to store data, formulas, charts, and formatting, making them lightweight and widely compatible with various versions of Excel and third-party spreadsheet programs.

The XLSX format uses a more efficient file compression method than the older XLS format, allowing for smaller file sizes. It is also more secure, as it does not contain executable macros, reducing the risk of malicious code being embedded in the file.

Why Convert XLSM to XLSX?

Converting from XLSM to XLSX can be useful for several reasons:

• Increased Compatibility: XLSX files are widely supported by most modern spreadsheet software, including Google Sheets and LibreOffice Calc. If you no longer need macros and want to ensure your file is accessible across various platforms, converting to XLSX is a smart choice.
• Security: Since XLSX files do not contain macros, they are inherently safer than XLSM files. Converting to XLSX removes any potential security risks associated with macro-enabled files, making it easier to share files without concerns about malicious code.
• Reduced File Size: XLSX files tend to be smaller in size compared to XLSM files, which may help reduce storage requirements and improve file-sharing efficiency.
• Simplified File Sharing: If you plan to share your file with others who may not need or understand the macros, converting to XLSX provides a simpler, easier-to-share version of your workbook.

How to Convert XLSM to XLSX

There are several ways to convert an XLSM file to an XLSX file. Below are the most common methods:

• Using Microsoft Excel: The easiest way to convert an XLSM file to XLSX 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 Workbook (*.xlsx).”
  6. Click “Save” to convert the file to XLSX. This process will remove the macros and save the workbook without them.
• Using LibreOffice Calc: LibreOffice Calc, an open-source alternative to Excel, can be used to convert an XLSM file to XLSX. Follow these steps:
  1. Open the XLSM file in LibreOffice Calc.
  2. Click on “File” and select “Save As.”
  3. Choose “Microsoft Excel 2007-2019 (*.xlsx)” from the file format options.
  4. Click “Save” to complete the conversion.
• Using Online Conversion Tools: Many online tools allow users to upload an XLSM file and convert it to XLSX. These tools are simple to use, though you should ensure that the service respects your privacy when uploading sensitive information. Most tools require you to select the XLSM file, choose the XLSX format, and download the converted file.
• Using Python (for Developers): If you need to automate the conversion of XLSM files to XLSX, you can use Python libraries such as `openpyxl` or `pandas`. Here’s an example of how to use Python to convert the file:

      import openpyxl
      wb = openpyxl.load_workbook('file.xlsm', keep_vba=False)
      wb.save('file.xlsx')
      

  This script will load the XLSM file, remove any macros, and save it as an XLSX file.

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

If you prefer to use Microsoft Excel for the conversion, here’s a simple guide:

1. Open your XLSM file in Microsoft Excel.
2. Click “File” in the menu bar and choose “Save As.”
3. In the “Save as type” dropdown, select “Excel Workbook (*.xlsx).”
4. Choose the location where you want to save the new file.
5. Click “Save.” The macro-enabled content will be removed, and the file will be saved as an XLSX file.

Benefits of Converting XLSM to XLSX

There are several reasons why converting XLSM files to XLSX files is beneficial:

• Better Compatibility: XLSX is a universally accepted file format that is compatible with a wide range of spreadsheet applications, ensuring that your file can be opened on various platforms without issues.
• Enhanced Security: By converting an XLSM file to XLSX, you remove any macros, reducing the risk of malicious code being executed. This makes XLSX files safer to share and work with, especially in environments with strict security protocols.
• Reduced File Size: XLSX files typically have smaller file sizes compared to XLSM files, making them easier to share, store, and manage.
• Simpler File Sharing: XLSX files are easier to work with for those who do not require the advanced functionality of macros, making them more suitable for general-purpose sharing and collaboration.

Things to Keep in Mind When Converting XLSM to XLSX

While converting XLSM to XLSX is a straightforward process, there are a few considerations to keep in mind:

• Loss of Macros: When you convert an XLSM file to XLSX, any macros (VBA code) will be removed. If the macros are essential to the functionality of the workbook, you may need to keep the XLSM format or manually rework the workbook to preserve the needed functionality.
• Formula and Data Compatibility: The conversion process will not affect the data and formulas in the workbook, but some advanced features that rely on macros might not work as expected once the macros are removed.
• File Size Reduction: XLSX files tend to have smaller file sizes compared to XLSM files, which can be beneficial when you need to save space or share the file more efficiently.

Conclusion

Converting XLSM files to XLSX is an ideal solution when you no longer need macros in your workbook or when you need to share the file in a more universally accepted format. Whether you’re using Microsoft Excel, LibreOffice Calc, or Python, the conversion process is simple and fast. By converting to XLSX, you can ensure that your workbook is compatible with a wide range of software while removing any security risks associated with macros. Remember, if your file relies heavily on macros, you might want to reconsider converting it to XLSX or explore other alternatives to preserve your VBA code.
