Frequently Asked Questions
Here are some common questions and answers about et file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Will frozen panes or headers stay after conversion?
A: Only in XLSX or ODS. PDF will lock the view, but CSV loses frozen rows and columns entirely.
Q: Can I convert Google Sheets to Excel?
A: Definitely! Just go to File > Download > Microsoft Excel (.xlsx) in Google Sheets. Two clicks and you’re back in Excel land.
Q: Do colors and highlights stay after conversion?
A: Only if you convert to formats that support formatting—like XLSX or ODS. CSV and TSV don’t keep colors.
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: 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: 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: Does RunConvert compress spreadsheet files?
A: We don’t compress them by default, but the resulting files are often smaller—especially if converting from XLS to XLSX or to CSV.
Q: Can I convert a spreadsheet with VBA code?
A: VBA doesn’t transfer to other formats. You’ll need to keep it in XLSM if the code matters.
Q: Does RunConvert support right-to-left languages like Arabic or Hebrew?
A: Yes! Just make sure your original spreadsheet is encoded in UTF-8. We handle RTL text without issues.
Q: Can I convert spreadsheets that contain dropdowns or validations?
A: Yes, but only to formats like XLSX or ODS. Those features don’t carry over to CSV or PDF.
