XLSX is Microsoft Excel’s flagship format, launched in 2007. It’s a spreadsheet file that organizes data in rows and columns, ideal for budgets, analytics, or tracking projects. Built on XML, XLSX is compact yet powerful, handling formulas, charts, and massive datasets. It’s the standard for number-crunchers, compatible with Excel, Google Sheets, and more. Ever juggled sales figures or planned an event? XLSX is likely your trusty sidekick. But sometimes, you need a simpler format for sharing or importing data.

CSV stands for Comma-Separated Values, a bare-bones format that stores data as plain text. Each row is a line, with values split by commas—think of it as a spreadsheet stripped to its essentials. CSV shines for importing into databases, apps, or programming scripts. It’s lightweight, universally supported, but lacks formatting or formulas. You’ve probably seen CSVs when exporting contacts or uploading data to CRMs. It’s like a no-fuss notepad for data, perfect for compatibility but not for fancy visuals.

Check if your app needs a specific delimiter (like semicolons); our tool lets you customize. Test the CSV in your target software to ensure it imports correctly. For multi-sheet XLSX files, convert one sheet at a time for clarity. Back up your original XLSX before converting. These steps keep your CSVs clean, functional, and ready for any platform.

XLSX to CSV conversions are usually smooth, but issues can arise. Data cut off? Check for special characters or commas in your XLSX—they can break CSV formatting. If the CSV won’t import, verify the delimiter matches your app’s needs. Complex formulas may not translate—flatten them to values first. Corrupted XLSX files? Open and save them in Excel before converting. Our tool at runconvert.com minimizes these problems, but always test your CSV. A quick tweak, and your data’s good to go.

XLSX files are larger but dynamic; CSVs are tiny and static. Think of XLSX as a fully loaded SUV and CSV as a zippy bike—one’s versatile, the other’s built for speed.
