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: 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: 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: Can I convert a CSV to Excel without losing data?
A: Yes! Just open the CSV in Excel and save it as an .xlsx file. Boom—done. Just double-check the formatting afterward to make sure it looks right.
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: 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: Is there a difference between .xls and .xlsx conversion?
A: .XLS is older and bulkier. .XLSX is newer, smaller, and faster. We recommend upgrading during conversion when possible.
Q: Does RunConvert compress spreadsheet files?
A: We don’t compress them by default, but the resulting files are often smaller—especially if converting from XLS to XLSX or to CSV.
Q: Does RunConvert modify my spreadsheet data?
A: Nope. We just transform the file structure—your original data stays untouched and private.
Q: Can I convert spreadsheets with multiple tabs?
A: Yes, but not all formats support multiple sheets. XLSX and ODS do, but CSV flattens everything into one sheet. If tabs matter, avoid CSV.
Q: Can I open a converted CSV on Google Sheets?
A: Of course! Just drag and drop the file into Google Drive and open with Sheets. Works like a charm.
