Frequently Asked Questions
Here are some common questions and answers about xlsx 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: Can I upload a file from a URL for conversion?
A: Not yet, but we’re exploring this feature. For now, you’ll need to download it and upload from your device.
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: Will pivot tables stay intact after conversion?
A: If you convert between Excel-compatible formats like XLSX or ODS, pivot tables should stay. CSV or PDF will flatten them to plain data.
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: Does converting a spreadsheet remove conditional formatting?
A: Depends on the output. XLSX and ODS usually preserve it. But CSV? Nope—it strips everything to plain text.
Q: How long does a spreadsheet conversion take?
A: Usually just a few seconds. It depends on your file size and internet speed, but it’s faster than brewing a cup of coffee.
Q: Can I convert a spreadsheet into a presentation format like PPT?
A: Not directly. You’d need to export data as images or copy tables manually into slides for now.
Q: Is there a limit on how many times I can convert?
A: No limits for basic use! Convert as many spreadsheets as you want—no strings attached.
Q: What if I accidentally upload the wrong file?
A: No stress—just hit back and upload the right one. We don’t store anything, so no damage done.
