Frequently Asked Questions
Here are some common questions and answers about xltx file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Why do I see weird characters after converting?
A: It’s likely a character encoding issue. Make sure your original file uses UTF-8 to prevent display glitches.
Q: Can I convert Google Sheets to Excel?
A: Definitely! Just go to File > Download > Microsoft Excel (.xlsx) in Google Sheets. Two clicks and you’re back in Excel land.
Q: Do I need an account to convert files on RunConvert?
A: Nope. No logins, no email walls—just upload your file and get your download. It’s as breezy as it gets.
Q: Can I convert an Excel macro-enabled file (.xlsm)?
A: Yes, but keep in mind most formats don’t support macros. If you convert to XLSX or CSV, the macros won’t carry over.
Q: Why do some numbers change when I open a converted file?
A: Sometimes Excel auto-formats things weirdly—like turning long numbers into scientific notation. Try formatting cells as text before converting.
Q: Can I convert a spreadsheet into JSON or XML?
A: RunConvert doesn’t support that just yet, but it’s on the roadmap. For now, you can use tools like Excel-to-JSON converters online.
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: 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 does my CSV look weird in Excel?
A: Ah, the classic comma confusion. Sometimes Excel misreads delimiters—especially if your system uses semicolons instead. Try importing the CSV using Excel's 'Data > From Text' feature and set the correct separator.
Q: Does converting spreadsheets affect file size?
A: It can! XLSX files are usually smaller than XLS. CSVs are super light, but lose features. PDFs can be bulky if there’s a lot of formatting or images.
