Frequently Asked Questions
Here are some common questions and answers about xls file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Can I convert a spreadsheet into an image?
A: RunConvert doesn't do images yet, but you can convert to PDF and then screenshot or use a PDF-to-image tool.
Q: What if my spreadsheet has images or charts?
A: Charts usually convert fine in spreadsheet formats, but images might not. And converting to CSV? Forget it—those are for numbers and text only.
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: Can I preview the file before downloading the converted version?
A: On RunConvert, we’re working on adding that feature. For now, just download it—it’s super quick, and if it’s not right, you can tweak and reupload.
Q: Can I translate a spreadsheet during conversion?
A: We don’t do translation (yet), but you can use Google Translate or another tool after converting.
Q: What if my converted file looks different?
A: That can happen—especially when jumping between formats that support different features. Just check your data and reformat if needed.
Q: How can I make sure the data types stay correct after conversion?
A: Great question! Keep consistent formatting in your original file—especially dates and numbers. And double-check after converting, just in case.
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 RunConvert faster than desktop apps?
A: In most cases, yeah! No software installs, no waiting. Just upload and go—it’s like a fast lane for your files.
Q: Why does my CSV look weird in Excel?
A: Ah, the classic comma confusion. Sometimes Excel misreads delimiters—especially if your system uses semicolons instead. Try importing the CSV using Excel's 'Data > From Text' feature and set the correct separator.
What is XLS (Excel Spreadsheet)?
XLS (Excel Spreadsheet) is a proprietary file format developed by Microsoft for storing spreadsheet data, including rows, columns, and data cells. The format supports complex data like formulas, charts, and formatting.
XLS files are widely used for business, academic, and personal tasks requiring advanced data analysis, visualization, and reporting.
How to open XLS?
XLS files can be opened using spreadsheet programs like Microsoft Excel, LibreOffice Calc, or Google Sheets. These programs display data in a tabular format, preserving the cell structures, formulas, and formatting.
