Frequently Asked Questions
Here are some common questions and answers about xls and ots file conversions asked by our users on RunConvert.com.
Frequently Asked Questions
Q: What’s an XLS file, and why convert it?
A: XLS is an older Excel spreadsheet format, still used by some. Converting to XLSX or PDF makes it shareable or modernized. RunConvert.com brings these files into the present.
Q: Why does my converted XLS look different?
A: Some older elements might not translate perfectly. It’s like copying a painting with modern tools. RunConvert.com does its best, but simplifying helps.
Q: Why does my converted OTS look different?
A: Some template elements might not translate perfectly. It’s like copying a painting with different brushes. RunConvert.com does its best, but simplifying helps.
Q: How fast is OTS conversion on RunConvert.com?
A: Quick as a snap—usually just seconds! OTS files are lean, so RunConvert.com processes them fast.
Q: What’s the best format to share spreadsheet data online?
A: If it’s just raw data, go with CSV—it’s light and loads fast. If you want to keep formatting, PDF or XLSX are your best bets. Depends who you’re sharing with and how much you want them to fiddle with it.
Q: Why do some formats lose cell formatting?
A: Some file types just don’t support that info. CSV, for example, only stores plain text—no colors, no borders, just the facts.
Q: Can I convert CSV files with semicolons instead of commas?
A: Yes! Our converter auto-detects separators. But if it doesn’t, just tweak the input settings when uploading.
Q: Can I open a converted CSV on Google Sheets?
A: Of course! Just drag and drop the file into Google Drive and open with Sheets. Works like a charm.
Q: Can I convert Excel macros too?
A: Short answer: not really. Most formats don’t support macros. So if you rely on those sweet VBA scripts, keep the file in Excel format.
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.
