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: Why would I need to convert a spreadsheet to PDF?
A: Sometimes, you want to share your data without others editing it. PDFs lock in the look and feel of your sheet, making it great for reports or presentations.
Q: Can I convert spreadsheets on my phone?
A: Yes! RunConvert is mobile-friendly, so you can convert files straight from your phone’s browser—whether you’re team iPhone or Android.
Q: Why is my converted CSV opening weird in Excel?
A: Excel can get picky about delimiters and encoding. Try opening it via 'Data > From Text/CSV' for better control.
Q: Can I convert Google Sheets using RunConvert?
A: Yes—just download your Google Sheet as an Excel, CSV, or PDF file first, then upload it to RunConvert.
Q: Why do I see weird characters after converting?
A: It’s likely a character encoding issue. Make sure your original file uses UTF-8 to prevent display glitches.
Q: Does converting spreadsheets affect file size?
A: It can! XLSX files are usually smaller than XLS. CSVs are super light, but lose features. PDFs can be bulky if there’s a lot of formatting or images.
Q: Will formulas work after conversion?
A: If you're converting to another spreadsheet format like ODS or XLSX, formulas usually transfer just fine. But CSV or PDF? Not so much—they flatten the data.
Q: Can I automate spreadsheet conversions using RunConvert?
A: Not yet, but we’re working on APIs for bulk or scheduled conversions. If you’re a dev or data nerd, stay tuned!
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.
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.

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.
