Frequently Asked Questions
Here are some common questions and answers about xltx file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
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: Do formulas still calculate after converting XLSX to ODS?
A: In most cases, yes. Excel and LibreOffice play nicely together—but complex macros or newer functions might act up a bit.
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: How do I fix broken rows or columns after conversion?
A: That’s often a delimiter issue. Try opening the file in a text editor to see if commas or tabs are breaking the layout, then import it properly.
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 does Excel show a warning when opening my converted file?
A: It’s common with non-Excel formats or CSVs—it’s just Excel being cautious. If the data looks good, you’re fine.
Q: Can I convert a CSV to Excel without losing data?
A: Yes! Just open the CSV in Excel and save it as an .xlsx file. Boom—done. Just double-check the formatting afterward to make sure it looks right.
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 multiple spreadsheets at once?
A: Totally. With batch conversion on RunConvert, you can upload a bunch of files and convert them all in one go. Saves time—and sanity.
Q: Can I customize the layout during PDF conversion?
A: Not yet—but we’re working on adding options like page size, orientation, and margins in future updates.
