Frequently Asked Questions
Here are some common questions and answers about xlsm file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Why do some numbers change when I open a converted file?
A: Sometimes Excel auto-formats things weirdly—like turning long numbers into scientific notation. Try formatting cells as text before converting.
Q: Why is my date format changing during conversion?
A: It’s usually a locale issue—some formats use MM/DD/YYYY, others DD/MM/YYYY. Be sure to set your region correctly before saving or converting.
Q: What’s the difference between XLS and XLSX?
A: Good question! XLS is the older Excel format, while XLSX is newer, smaller, and more efficient. It’s kind of like upgrading from a flip phone to a smartphone.
Q: Are converted files virus-free?
A: Absolutely. We don’t add anything to your files—just convert them. Always scan downloads if you’re extra cautious though!
Q: Is spreadsheet conversion free on RunConvert?
A: Totally free. No hidden fees or credit cards—just a clean, simple conversion experience.
Q: What’s the cleanest format for archiving spreadsheets long term?
A: PDF/A is a solid pick for archiving. If you want something editable, stick with ODS—it’s open and standardized.
Q: Why are some formulas broken after converting?
A: Not all formats use the same formula syntax. Stick to XLSX or ODS for the best compatibility.
Q: Can I convert an Excel macro-enabled file (.xlsm)?
A: Yes, but keep in mind most formats don’t support macros. If you convert to XLSX or CSV, the macros won’t carry over.
Q: Why use spreadsheet conversion at all?
A: Sometimes you need a lighter file, better compatibility, or just a shareable version. Conversion keeps your data flexible and accessible.
Q: Is it safe to convert spreadsheets online?
A: Yep, as long as you're using a trusted service like RunConvert. We don’t keep your files after conversion, and everything’s encrypted. Your secrets are safe with us!
What is XLSM (Excel Macro-Enabled Spreadsheet)?
XLSM (Excel Macro-Enabled Spreadsheet) is a Microsoft Excel file format that allows users to store spreadsheets with embedded macros. Macros are small programs or scripts used to automate repetitive tasks within Excel.
XLSM files are commonly used by advanced users who want to extend Excel’s functionality through custom code written in Visual Basic for Applications (VBA). These files are useful for automating complex tasks or workflows.
How to open XLSM?
XLSM files can be opened using Microsoft Excel. Simply double-click the file, and it will open in Excel. When opening an XLSM file, Excel will prompt you to enable or disable macros, depending on your security settings.
If you do not have Excel, you can also open XLSM files in LibreOffice Calc, but macros will not be supported.

When converting to formats like CSV, keep in mind that macros will be lost since they are not supported in those formats.
What is OTS (OpenDocument Template Spreadsheet)?
OTS (OpenDocument Template Spreadsheet) is a file format used for creating templates in spreadsheet applications, such as LibreOffice Calc or OpenOffice Calc. It allows users to create predefined spreadsheet structures that can be reused and customized for various tasks.
OTS files store formatting, formulas, and other spreadsheet elements, but unlike regular spreadsheet files, they serve as templates that can be used to generate new documents with the same structure.
How to open OTS?
OTS files can be opened using spreadsheet programs that support the OpenDocument format, such as LibreOffice Calc or OpenOffice Calc.
To open an OTS file, simply double-click the file or open it from within the spreadsheet application. Once opened, you can create new documents based on the template.
