Frequently Asked Questions
Here are some common questions and answers about xls file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Can I convert a spreadsheet with VBA code?
A: VBA doesn’t transfer to other formats. You’ll need to keep it in XLSM if the code matters.
Q: Why is my date format changing during conversion?
A: It’s usually a locale issue—some formats use MM/DD/YYYY, others DD/MM/YYYY. Be sure to set your region correctly before saving or converting.
Q: How can I make sure the data types stay correct after conversion?
A: Great question! Keep consistent formatting in your original file—especially dates and numbers. And double-check after converting, just in case.
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: Will text wrapping be preserved after conversion?
A: Yes, as long as the format supports it. PDF, XLSX, and ODS usually preserve wrapping. CSV won’t.
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.
Q: What’s the safest format to share with non-tech users?
A: PDF is the safest—it's readable, uneditable, and works on almost every device without special software.
Q: Does RunConvert have file size limits?
A: We allow generous file sizes, but there’s a cap (around 100MB for now). Most spreadsheets fall well under that, 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.
Q: Can I batch convert multiple spreadsheets at once?
A: Right now, RunConvert handles one file at a time. But batch conversion is in the pipeline, so stay tuned!
