Frequently Asked Questions
Here are some common questions and answers about xlsb file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Can I convert a spreadsheet into JSON or XML?
A: RunConvert doesn’t support that just yet, but it’s on the roadmap. For now, you can use tools like Excel-to-JSON converters online.
Q: Are my spreadsheet files stored permanently on RunConvert?
A: No way. Files are deleted shortly after conversion—we don’t keep copies, and we don’t snoop. Your data’s your business.
Q: Can I convert scanned spreadsheets?
A: Not directly. Scanned files are usually images or PDFs, so you’d need OCR (optical character recognition) first—then convert.
Q: What happens to merged cells during conversion?
A: Merged cells usually keep their formatting in XLSX and ODS. In CSV though? They’ll get split into separate cells.
Q: Do I need an account to convert files on RunConvert?
A: Nope. No logins, no email walls—just upload your file and get your download. It’s as breezy as it gets.
Q: Why do some formats lose cell formatting?
A: Some file types just don’t support that info. CSV, for example, only stores plain text—no colors, no borders, just the facts.
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: Is there a difference between .xls and .xlsx conversion?
A: .XLS is older and bulkier. .XLSX is newer, smaller, and faster. We recommend upgrading during conversion when possible.
Q: Can I remove empty columns before converting?
A: You’ll need to do that manually before uploading. We’re planning to add a cleanup tool in the future!
Q: Can I convert CSV files with semicolons instead of commas?
A: Yes! Our converter auto-detects separators. But if it doesn’t, just tweak the input settings when uploading.
What is XLSB (Excel Binary Workbook)?
XLSB (Excel Binary Workbook) is a file format used by Microsoft Excel for storing spreadsheet data in a binary format. Unlike the more common XLSX format, which is XML-based, XLSB stores data in a binary structure, making it faster to open and save for large workbooks.
XLSB files are typically used for large and complex Excel workbooks that require faster processing and lower file sizes.
How to open XLSB?
XLSB files can be opened using Microsoft Excel (Excel 2007 and later). You can simply double-click the file to open it, or use the 'Open' option in Excel's file menu.
XLSB files are not compatible with some other spreadsheet programs like Google Sheets. However, they can be opened in Excel, which is the recommended program.
XLSB is Developed by: Microsoft

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.
