Frequently Asked Questions
Here are some common questions and answers about ots file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
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 convert Excel to Numbers for Mac?
A: We don’t output Numbers format directly, but you can convert to CSV or XLSX and open it in Apple Numbers without a hitch.
Q: Can I preview how the PDF will look before converting?
A: We’re building a live preview feature! For now, you’ll need to download and check—conversions are quick, so it’s easy to retry.
Q: What’s the most universal spreadsheet format?
A: CSV, hands down. It’s readable by almost every spreadsheet program, script, and database. It’s the Swiss Army knife of spreadsheet formats.
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: 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: Why use spreadsheet conversion at all?
A: Sometimes you need a lighter file, better compatibility, or just a shareable version. Conversion keeps your data flexible and accessible.
Q: How do I fix broken rows or columns after conversion?
A: That’s often a delimiter issue. Try opening the file in a text editor to see if commas or tabs are breaking the layout, then import it properly.
Q: What format should I use for importing into Excel?
A: XLSX is the native format, but Excel also works great with CSV and ODS.
Q: What’s the best format for importing data into databases?
A: Usually CSV. It’s clean, lightweight, and plays nice with MySQL, PostgreSQL, and pretty much every database on the block.
