XLSX Converter
XLSX is the standard Excel format since Microsoft Office 2007. If you're working with spreadsheets, you're probably working with XLSX files. It replaced the older XLS format and brought significant improvements - smaller file sizes, better reliability, and support for more rows and columns. The format handles everything you need in a spreadsheet. Multiple sheets in one file, formulas that calculate automatically, charts and graphs, conditional formatting, pivot tables - all the tools people use for data analysis and financial modeling. XLSX files work across Windows, Mac, and even mobile devices, making them the go-to choice for sharing spreadsheet data. Converting XLSX files is common in a few scenarios. Maybe you need a simple CSV file to import data into another system. Or you're sharing with someone who uses LibreOffice and ODS format works better for them. Sometimes you just need to extract the data from an old XLSX file into a more accessible format. Whatever the reason, converting between XLSX and other formats keeps your data accessible.

Common Questions
What's the difference between XLSX and XLS?
XLSX is newer (2007+), creates smaller files, and handles more data. XLS is the legacy format from older Excel versions.
Can I convert XLSX to CSV?
Yes, though CSV only keeps data from one sheet and doesn't preserve formulas or formatting.
Will formulas work after conversion?
Depends on the target format. Converting to XLS or ODS keeps formulas. CSV and PDF don't support formulas.
Is this free?
Completely free with no file size limits.
Can I convert password-protected files?
You'll need to remove password protection first, then convert the file.

Formats like XLS and ODS preserve multiple sheets. CSV exports only the active sheet.
