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: Can I add a watermark to a spreadsheet before converting to PDF?
A: Not on RunConvert (yet!), but you can add it in Excel first—or use a PDF editor after converting.
Q: Will colors and fonts transfer in my spreadsheet conversion?
A: That depends on the format. Excel to Excel? You’re good. But converting to CSV? Say goodbye to colors, fonts, and anything fancy—it’s just plain text there.
Q: Can I convert spreadsheets without internet access?
A: Not with RunConvert—it’s a web-based tool. But if you need offline options, software like LibreOffice or Excel can do basic conversions.
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: Will formulas work after conversion?
A: If you're converting to another spreadsheet format like ODS or XLSX, formulas usually transfer just fine. But CSV or PDF? Not so much—they flatten the data.
Q: Do charts survive conversion to PDF?
A: Yup! Charts are usually preserved as visuals when you go XLSX → PDF. Just make sure they’re not floating off the page.
Q: Do hyperlinks survive spreadsheet conversion?
A: Yes, if you’re using formats like XLSX or ODS. In PDFs, they often still work. In CSVs though, you’ll just see plain text URLs.
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.
Q: Does spreadsheet conversion change my data?
A: Most of the time, no—but formatting might look a little different depending on the file type. For example, CSV doesn’t support bold fonts or colors, just raw data.
Q: Why are empty rows showing up in my converted file?
A: Your original file may have hidden rows or formatting. Try cleaning it up first before converting.
