Frequently Asked Questions
Here are some common questions and answers about spreadsheet file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
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: Do converted files work with Excel alternatives like LibreOffice?
A: Yes! Just make sure you pick a format LibreOffice supports—like CSV, XLSX, or ODS—and you’re good to go.
Q: Can I convert scanned spreadsheets?
A: Not directly. Scanned files are usually images or PDFs, so you’d need OCR (optical character recognition) first—then convert.
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: 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: Is spreadsheet conversion free on RunConvert?
A: Totally free. No hidden fees or credit cards—just a clean, simple conversion experience.
Q: What’s a TSV file, and how’s it different from CSV?
A: TSV stands for Tab-Separated Values, while CSV uses commas. They’re pretty similar—just different flavors of the same idea: plain text tables.
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: Are converted files virus-free?
A: Absolutely. We don’t add anything to your files—just convert them. Always scan downloads if you’re extra cautious though!
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.
